does anyone know about the capabilities of gripen's ericsson radar??
PS-05/A multimode radar (Sweden), Airborne fire-control radars
Type
I/J-band (8 to 18/20 GHz) multimode search and fire-control radar.
Description
PS-05/A is the multimode search and fire-control radar that is installed in the JAS-39 Gripen multirole combat aircraft and in its baseline form, comprises a 25 kg antenna/platform assembly, a 73 kg power liquid-cooled, travelling wave tube power amplifier/transmitter unit, a 32 kg software-controlled exciter/receiver unit and a 23 kg signal/data processor. Within this latter unit, the signal processing function is programmable, while the D80 data processor uses software written in Pascal and incorporates a built-in test routine. To provide the required operational flexibility, low, medium and high Pulse Repetition Frequency (PRF) functions are incorporated together with a range of waveform modes which include the following:Air-to-Ground Ranging (AGR)A ground target ranging mode.Doppler Beam Sharpening (DBS)A synthetic aperture mode that utilises Doppler processing and is used for high-resolution ground mapping with high angular coverage obtained via continuous antenna scanning.High Pulse Doppler (HPD)A high PRF mode that utilises Doppler processing for clutter rejection and which is designed primarily for use against forward hemisphere air targets.Low Pulse Doppler (LPD)A Doppler processing mode that is used against moving surface targets.Low Pulse Repetition Frequency (LPRF)A low PRF mode with pulse-to-pulse frequency agility that is used for real-beam mapping and surface target detection.Medium Pulse Doppler (MPD)A medium PRF mode that utilises Doppler processing and is designed for use against nose and tail aspect air targets. A high-resolution submode is incorporated to facilitate target tracking.SpotLight Mode (SLM)A synthetic aperture spotlight mode that utilises Doppler processing for very high-resolution mapping.Use of these various waveform/PRF combinations allows the

The PS-05/A is a pulse-doppler radar currently used by the JAS 39 Gripen fighter aircraft. It weighs 156 kg and has been developed by Ericsson and GEC-Marconi, based on the latter's advanced Blue Vixen radar for the Sea Harrier (which inspired the Eurofighter's CAPTOR radar as well).
The PS-05/A works in the 8-10 GHz band and has 1 kW energy output (> 10 kW maximum output). The radar is capable of detecting, locating, identifying and automatically tracking multiple targets in the upper and lower spheres, on the ground and sea or in the air, in all weather conditions. It consists of four parts and all parts can be replaced in 30 minutes.
Gripen operator Hungarian Air Force reported the PS-05 radar set has proved reliable so far, both in domestic service and NATO flight exercises in Corsica.
Versions
MK-3
Is the latest version of PS-05/A radar which is currently in use and has been available since 2005.
It is capable of detecting a fighter aircraft from 120 km distance and can see road traffic and count ships at anchor in a harbour at 70 km. The radar weighs 156kg made up of a 25 kg antenna/platform assembly, a 73 kg power liquid-cooled, travelling wave tube power amplifier/transmitter unit, a 32 kg software-controlled exciter/receiver unit and a 23 kg signal/data processor.

Radar modes:
a) Air-to-Air modes:
LRS (Long Range Search) is used to detect and identify targets at high ranges.
TWS (Track While Scan) allows to track targets and search for other targets.
MPTT (Multiple Priority Target Tracking).
PTT (Priority Target Tracking) allows accurate targeting and tracking Air-to-Air missiles.
STT (Single Target Track).
ACM (Air Combat Mode) is used for automatic target detection in dogfight.
b) Air-to-Surface modes:
LRS (Long Range Search) is used for ground or sea target search at long distances.
RA (Raid Assessment) ensures bombing.
SMTI (Stationary and Moving Target Indication) is used for ground stationary or moving targets.
GSPTT (Ground and Sea Priority Target Tracking).
GM (Ground Mapping) ensures mapping of terrain under the aircraft for navigation purposes (e.g. terrain copying at night or adverse weather condition).
HRM (High Resolution Mapping) ensures terrain mapping by synthetic aperture in order to gain high resolution pictures.
RANGING high accuracy ground target ranging.
All information is processed by a Mercury Computer Systems RACE/PPC setup, which has replaced the Ericsson D80 of Batch 1-2 Gripens.
MK-4
Is an upgraded version of MK-3 and should improve SAR capability to modern standards and enhance GMTI/GMTT (SMTI/GSPTT) modes.
MK-5
Is a further upgrade of MK-4 radar which will gain new AESA antenna instead of mechanically scanned antenna. This radar will be available by 2012.
Development of the AESA radar for Gripen started out under the Saab Ericsson NORA (Not Only a RAdar) programme, and has been underway for several years, including test flying aboard a specially-retained Saab JA 37 Viggen testbed. Benefits of the NORA concept was the provision of improved long-range tracking as a result of the combination of longer detection range and electronically-steered beam control, dominant battlespace awareness, track identification through non-co-operative target recognition, low probability of intercept and enhanced jamming capabilities. The AESA radar programme is directly linked to MIDAS (Multifunction Integrated Defensive Avionics System), which will also add electronic attack and advanced datalinking capabilities.
