The country’s leading radar house is Israel Aerospace Industries Elta Systems division, known as IAI Elta. The firm provides the EL/M-2084 multi-mission radar for the Iron Dome and David’s Sling air defence systems. This three-dimensional radar uses an Active Electronically Scanned Array (AESA) antenna and performs either sector scanning
across a 120° area, or full 360° scanning at 30 revolutions-per-minute. When operating in the air surveillance role, the radar can detect targets at a range of 256nm (474km) and at altitudes of up to 100,000 feet. When operating in a weapons-location mode, it detects targets at a range of 54nm (100km). The radar can detect and track up to 1,200
targets in its air defence mode, and 200 targets-per-minute when performing weapons location.

Here is what 2084 being a single low cost radar solution helps israel with multi tier defense
Now Consider
Pantsir System
The Pantsir-S1 fire control system includes a target acquisition radar and dual waveband tracking radar
The most recent Pantsir S1 variant has two passive phased array radars to provide a robust capability to acquire, track and concurrently engage up to four targets, such as AGM-88 HARM/AARGM missiles, cruise missiles, JDAMs, SDBs or other PGMs. This image shows the S-band VNIIRT 2RL80 acquisition radar deployed, and the 1RS2-1 Ku-band engagement radar elevated (KBP).
Early variants of the SA-19 Grison were developed to defend land manoevre forces against missile firing attack helicopters and low flying close air support fighters. More recently, the re-engineered and modernised Pantsir S1 has seen the role of the system redefined to protection of high value targets against precision guided munitions and cruise missiles.
The development of the Pantsir S/S1 saw the introduction,
initially, of a search radar with a doubly curved parabolic surface and eliptical shape. This was supplanted in production variants with a VNIIRT developed phased array. The latter design has since appeared on 2K22M1 Tunguska M1 demonstrators, as well as tracked and wheeled 96K6 Pantsir S1 demonstrators and production systems.
The VNIIRT developed PESA technology acquisition radar on the Pantsir S1, the 2RL80/2RL80E, uses a mechanically rotated 1776 x 940 mm sized 760 kg passive S-band phased array. The design provides elevation coverage between 0° and 60°, range coverage between 1 and 50 km, and performs a circular scan in 2 or 4 seconds. The radar can initiate tracking in 2 seconds.
Cited detection range performance for a 1 m2 target is 47 km, for a 0.1 m2 target is 26 km. Cited clutter rejection is 55 dB. Accuracy figures cited are 50 metres in range, 15 - 18 min of arc in azimuth, and 25 - 30 min of arc in elevation.
Elevation coverage is selectable in increments of 0° - 60°, 0° - 30°, 40° - 80° and 0 - 25°, and the radar can search a 360° circle at 15 or 30 RPM. Range coverage can be selected in several modes, at 1-30 km, 1-50 km, 1-25 km and 3-80 km.
Acquisition performance for various target types has also been cited, with notable inconsistencies:
- 36 km for a small fighter with a 2 m2 RCS;
- 20 km for a manoeuvring cruise missile with a 0.1 m2 RCS;
- 16 km for a glidebomb with a 0.2 m2 RCS;
- 12 km for an AGM-88 HARM anti-radiation missile with a 0.1 m2 RCS;
- 32 km for an AH-64 Apache attack helicopter.
The evolution of engagement radars in the Pantsir series has seen three distinct designs.
Early Pantsir S1 demonstrators initially used an MMW band monopulse tracking antenna, with a characteristic conical radome, with the Russians claiming two discrete Phazotron designs in this configuration, the 1L36-01 Roman and later 1RS2-E Shlem.
This pulse Doppler radar is designated the 1RS2/1RS2-E Shlem or SSTsR (Stantsiya Slezheniya Tsel'a i Rakety - Target and Missile Tracking Station), initially designated the 1RS1 and 1RS1-E for export. Cited tracking range performance for a 2 m2 target is 30 km. Cited RMS angular errors for X-band operation are 0.3-0.8 milliradians, for Ku-band operation 0.2-0.4 milliradians, with a 5 metre range error.
The X-band component of the SSTsR is used for target tracking, and uplink of missile steering commands., the Ku-band component for target and missile beacon tracking. The system typically guides one or two missile rounds against a single target.
T
his design has since appeared on the 2K22M1 Tunguska M1 demonstrators, various repackaged Pantsir variants on smaller chassis, usually with the 2RL80E acquisition radar.
In 2004 the requirement for the PVO engagement radar changed, when it was expected that the program would be cancelled. A new requirement was issued to increase the number of concurrent targets to be tracked and engaged, and engagement range was increased. This likely reflects the success of the US GBU-31/32/35/38 JDAM and emergence of analogues globally, where more than two weapons would be released from an aircraft concurrently. With the GBU-39/B Small Diameter Bomb intended to be released eight at a time, the Roman and Shlem would be saturated in a single aircraft attack.
This resulted in the development of an entirely new PESA based radar, curiously designated the
1RS2-1 / 1RS2-1E, but also labelled by a Russian source as the 1RL123-E. VNIIRT has been credited with the development of this design. To date all imagery has excluded views of the PESA antenna without the protective radome, so the following description is based on recent public disclosures and is yet to be validated:
- Operating centre wavelength claimed by KBP to be “8 mm in the K-band” - antenna geometry suggests 15 mm (20 GHz) to 18 mm (16.7 GHz);
- Beamsteering angles of up to ±45° of arc;
- Mechanical PESA boresight steering in elevation between -5° and 82°;
- Track while scan of nine separate targets;
- 90% probability of initial target acquisition within 1 second of coordinate transfer from the 2RL80 with errors of ±2.5° in azimuth, ±2.5° in elevation, ±200 m in range and ±60 metres / sec in radial velocity;
- Tracking errors of 0.2 milliradians in azimuth, 0.3 milliradians in elevation, 5 metres in range and 2 metres / sec in velocity;
- Ability to track airborne targets at velocities between 10 to 1,100 metres / sec;
- Ability to capture 4 missiles after launch;
- Ability to track 3 to 4 outbound missiles at velocities between 30 to 2,100 metres / sec;
- Detection range of 24 km against a 2.0 m2 RCS airborne target; 21 km against a 1 m2RCS airborne target; 16 km against a 0.5 m2 RCS airborne target; 10 km against a 0.1 m2 RCS airborne target; 7 km against a 0.03 m2 RCS airborne target;
High countermeasures resistance is claimed for the 1RS2-1 and 2RL80, but not detailed beyond the standard descriptions found in brochures.
The primary antenna is used for target and missile tracking, it is supplemented by a command link antenna which is part of the APKNR (Apparatura Peredachi Komand i Naprovadzaniya Raket) subsystem for datalink control of the missiles.
The 1L36-01 Roman was the first
engagement radar used on the Pantsir S demonstrators. The characteristic conical radome shape conceals a parabolic reflector antenna with a quad waveguide feed for dual plane monpulse angle tracking, with
X-band and Ku-band channels. Note the smaller upper missile command link antenna. The radar has been labelled as a 96L6-1, but more commonly as the 1L36-01 (© 2007, Yevgeniy Yerokhin, Missiles.ru).
The
1RS2-E Shlem was the second engagement radar used on the Pantsir S demonstrators, it continues to be offered with Pantsir and Tunguska variants on tracked chassis where its compact size and single target limitation do not present operational problems. The antenna has not been displayed without the radome, but is likely to be very similar to the earlier 1L36 Roman series (© 2005, Said Aminov, Vestnik PVO).
Detail of new Pantsir S1 1RS2-1 / 1RS2-1E PESA engagement radar, which is claimed to operate in the
Ku-band. The small upper antenna belongs to the APKNR (Apparatura Peredachi Komand i Naprovadzaniya Raket) subsystem for datalink control of the missiles. The design has been credited to VNIIRT (KBP).

Now comes the most important part? Which one suits us better?
Lets see simply this to first understand the basis
View attachment 296646
Now simply compare few things
Spyder 2084 - S Band
Pantsir- Combination of Acquisition Radar - 2RL80/2RL80E S Band and engagement radars 1RS2-1/1E operating in X, Ku and K Band
Further
- Aerospace engineers designed stealth airplanes primarily to beat the detection equipment that poses the greatest threat—X-band radar.
- Surface-to-air batteries use this band because it operates at wavelengths that give the optimal compromise between the range and resolution needed to identify and track a target.
- But when stealth airplanes are exposed to radar waves longer than this wavelength range, they generate stronger radar returns.
- The beauty of this system which uses multiple wavelength is that jamming is much more difficult.
Thus that is why, we require a combination.
Consider the best Long range radar in S-400 - Nebo M
- The Nebo-M includes three truck-mounted radar systems, all of them -AESAs: the VHF RLM-M, the RLM-D in L-band (UHF) and the S/X-band RLM-S. (Russian documentation describes them as metric, decimetric and centimetric—that is, each differs from the next by an order of magnitude in frequency.)
- Each of the radars is equipped with the Orientir location system, comprising three Glonass satellite navigation receivers on a fixed frame, and they are connected via wireless or cable datalink to a ground control vehicle.
So you see, we need a combination for taking on ARM and CMs and such very stealthy incoming threats..
