Russian mechanics and American tech, should be comparable to US Awacs
India has officially taken delivery of an Awacs early-warning surveillance aircraft, part of a $1bn (£600m) defence deal with Israel. The plane, Russian-made but packed with Israeli radar, is expected to reinforce India's maritime security following the attacks on Mumbai last year.
The Radar System Improvement Program (RSIP) was a joint U.S./NATO development program.[1] RSIP enhances the operational capability of the E-3 radar electronic counter-measures, and dramatically improve the system's reliability, maintainability and availability.[1] Essentially, the program replaced the old TTL and MECL logic that was no longer available, with off-the-shelf computers. These computers being programmed in a high-level language instead of assembler. The real improvement comes from replacing the old 8-bit FFT with a 24-bit FFT, and the 12-bit A/D (Sign + 12-bits) with a 15-bit A/D (Sign + 15-bits). [7] These hardware and software modifications improve radar performance, and provide enhanced detection with an emphasis toward low radar cross section (RCS) targets.[1]
