Found Blue Hawk info, from International Defense Review, 8&9 1992.
X-band, high, medium and low PRF pulse-Doppler radar. 44nm look up range, 27nm look down. Ground mapping 120 degree sector to 80nm. Air cooled, 107kg weight, 2.5kVA prime power output, waveforms transmitted at 8kW peak and 160W mean from ring bar TWT, PRF 800Hz-90KHz. Four LRUs, plus planar antenna with three direct drive DC motors. Separate programmable signal, data and display processors (RDP 68020) using 'C' language for data and display processing and assembler for signal processing. 1553B databus and HOTAS compatible.
Modes - look up, look down, velocity search, HUD FOV, single target track, DBS, freeze display, surface track, two sea search modes. Could be expanded to include AMRAAM, TWS, GMTI, NCTR and TA.
Aimed mainly at retrofits, no antenna size given but seems similar to Grifo/Elta 2032 so I assume it could be tailored to fit applications. I assume it was aimed at the same market Ferranti's 4510 HUD, MED 2060 and FINAS sytems were aimed at - Mirage III/V, F-5, Mig-21, Skyhawk etc, plus new light aircraft such as Hawk 200. Expected to be ready for service in 1995 - the articles include pictures of a space model and an antenna on test.
Also found a recent online mention of it being currently considered for Pakistan's FC-1 fighters, but assume the new Selex Vixen 500E is more relevant.
So, it seems to fill the gap between Blue Fox and Blue Vixen, but no sales it seems.
