As you still seems to missunderstand why I have doubts about the 360°
radar coverage of Erieye let me try to explain it in a different way.
The Dassault Rafale in the latest version uses the RBE 2 AA AESA radar. This radar is in the nose, pointed to the front and offers detection and tracking in an area of 120°. It is able to detect fighters at distances of 75 nm/138,9 KM, the tracking range is 60nm / 111,12Km. It is able to track 40 targets at the same time and engage 8 of them. So far about the radar capabilities, but the Rafale offers more!
It also has the Spectra EWS, which is an integrated self-defense suite (or Electronic Counter Measure) that combines several sensors to detect and warn about hostile radars, missiles, and lasers. And here comes the most interesting point,
it offers 360° coverage!
Other features are:
passive, all-weather reliable, long-range detection, identification and geographical location of threats in the infrared, electromagnectic and electro-optical ranges. It uses short response times and cutting-edge defensive measures based on a combination of jamming, decoying and evasive maneuvers and technologies, such as Digital Radio Frequency Memory (DRFM) for signal processing...
The angular localization performance of Spectra makes it possible to precisely discover ground threats and to target them for immediate destruction with precision-guided munitions. In this totally passive mode, Spectra is also used as a general awareness and intelligence reporting system.

Let me point out the main points of Rafale and Erieye again:
Radar system performance Rafale:
- active electronically scanned array radar
- 138,9 Km range
- can detect and track air and ground targets in an area of 120° to the front
- uses phased array antennas for IFF
Radar system performance Erieye:
Active Phased Array Pulse Doppler multi-mode radar
450 km range and above 20 km (65,000 ft) altitude coverage
Effective surveillance area of 500,000 sq km
Capable of combined air and sea surveillance
Automatic tracking of priority air targets
Identification Friend or Foe (IFF) system
Saab - Products A-Z
- detection and tracking to an area of 150° to both sides
EWS/ECM performance Rafale:
- 360° coverage
- Radar, missile and laser warning
- engaging by jaming, or using chaff and flares
ESM system performance Erieye:
360º azimuth coverage
High sensitivity
Wide band
High accuracy
Radar warning
SPS control/management
Radar Warning Receiver (RWR), chaff and flares
SPS also features Missile Approach Warning
(MAW), Laser Warning System (LWS) and
optional ESM and Integrated Defensive Aids Suite
(IDAS) with selection of low/medium/high bands
As you can see in both cases the
radar don't provide 360° coverage, it only provides coverage in the area where the radar arrays are.
But 360° coverage is available in both cases for ESM, or ECM which is pretty much the same (detecting and engaging radar, missiles and laser threats), but has nothing to do with the performance of the radar!
As I pointed out earlier, if PAF's new Erieye really is more improved that the Greek/Brazil Erieye system and achieves 360° radar coverage, there must be more radar arrays (like the Etiam Phalcon, or the Boeing Wedgetail), or something else that is new. But the latest pics that were posted here, don't show any changes on the airframe that could hint to such capabilities.
That's why I have some doubt about it so far and asks for other explainations, how that could be achieved.
