TheiC,
Thanks for that razor-sharp exposé of IAR's cutting-edge technology.
Besides being very informative, you have corrected a fundamental misapprehension of mine. I had been working on the assumption that our famous fighter pilot was using his AI.23 radar, with Mod 42 incorporated, which enabled the now well-known Google Image Search Mode.
This mod was developed by retired Ferranti engineers as private-venture. While ultimately successful, the marriage of 1950s analogue technology with Google's latest digital techniques required several technical compromises. In particular, analogue delay-lines had to be incorporated, which meant that several passes were required before the target image was sufficiently well defined and could be locked onto.
By the time, lock was acheived, the pilot would often be approaching Bingo fuel state and would have to pass the target to other image-seeking assets, using the code words Oscar Hotel.
