The E-RES arises from the proven need to accurately validate a new Radar or Seeker before their operational deployment. In particular, the greatest need is to evaluate their performance in terms of:

• Tracking/Detection capabilities and accuracy
• ECCM (Electronic Counter Counter Measure)

For this purpose, the initial test environment is undoubtedly the Laboratory, since, being controlled, it allows performance validations with high level of accuracy. However, E-RES can be used also for final field testing in hybrid environment.

With this in mind, ELDES has developed E-RES, boasting of being the only reliable source in the world for closed-loop simulation for Radar/Seeker assessment.

The E-RES system is able to generate, in real RF frequency, the Radar environment, consisting of:

• Single Scatter or Multi-Scatter targets
• ECM Techniques
• Clutter
• Chaff and Decoy

The E-RES, suitable to test any type of Radar, including Seekers and Imaging Radars (SAR/ISAR), can be connected to the Radar-Under-Test in two ways:

• inside an anechoic chamber with “Over-the-Air” (OTA) connection, or;
• with “Straight-on-Cable” connection, emulating the antenna of the Radar-Under-Test

The E-RES technology is based on the ultimate DRFM (Digital Radio Frequency Memory) methodology, created to perform the electronic warfare functions of the active Electronic Attack type. DRFM techniques are typically used to deceive radars, memorizing an incoming radio signal in numerical format, to then be able to reconstruct it with the best possible fidelity and possibly retransmit it.

In the E-RES system DRFM is based on a State-of-the-Art COTS VPX boards featuring A/D – D/A ultra-fast sampling; each DRFM Chassis can host up to 4 DRFM boards, 1 SBC and 1 Optical-Fiber Multi-Channel Communication board.

One of the main aspects of E-RES technology is to be able to emulate multiscatter targets, thanks to the very wide instantaneous bandwidth. The scatterers location can be programmed by means of a specific graphic software.

E-RES shall reproduce for each scatterer the proper amplitude and Doppler according to the Scenario motion and platforms attitude (Roll, Pitch and Yaw). Furthermore, the scatters programming can also be performed on SAR / ISAR targets, on the respective 3D graphic image

E-RES is a COTS (Commercial-off-the-shelf) product that does not require specific design and development, that can be customized according to Customer’s need, representing without doubt the ultimate and most effective way to assess Radar/Seeker.
