actually i cant seem to find an open source on it, but i have an old one, and things have changed since then.
Here are some excerpts from an article published by the Journal of Electronic Defense:
“Batch 1 Gripens also received the Rockwell Collins (San Juan, CA) (then Kaiser Electronics) head-up display (HUD) and the Ericsson Microwave (Gothenburg, Sweden) PS-05/A radar. The radar was equipped with a parabolic monopulse antenna developed from the UK’s Blue Vixen radar employed by the Sea Harrier FRS.2. The antenna was developed by BAE Systems (then GEC Marconi). Initially, the radar had a range of about 100 km, more or less equal to the Russian MiG-29, the Gripen’s potential opponent. However, the larger MiG-29 has a higher radar cross-section than the Gripen, which enables the latter to detect its adversary earlier and gain tactical advantage. The PS-05/A radar on the Batch 1 aircraft used the Ericsson D-80 processor, enabling it to track up to six airborne targets simultaneously and engage up to four of them with the use of AIM-120B AMRAAM missiles. Batch 1 aircraft avionics were integrated with two mission computers, SC-1 and the SMU, and three Mil-Std 1553B data buses.
The next 76 single-seat aircraft were built to the Gripen A Batch 2 standard. They were much improved and represented the first fully operational standard. The avionics system received a single (but more capable) Ericsson mission computer. The radar received a new EP-80E processor, increasing the number of targets that could be tracked simultaneously to 10. Now the radar could perform long-range search; track while scan (TWS); multiple priority target tracking; short-range, wide-angle search and track (combat-maneuver mode); single-target track; and raid assessment. In the air-to-ground mode, the radar could perform long-range search; land and naval priority target track; ground mapping; and surface ranging (for the gun and unguided rockets).
But above all, the Batch 3 is to receive a new Ericsson PS-05/A Mk3 radar, which has just been developed. The radar has a new D-96A high-speed processor with greatly increased computing power. This has enabled some new modes to be incorporated, as well as the ability to track in excess of 20 targets simultaneously (the precise number is classified). The radar range reaches 130-160 km, depending on various factors. In air-to-air search mode, a pilot can select among three patterns of search: 2×120º, 2×60º, or 4×30º. The search rate is 60 degrees per second. An improved radar transmitter and receiver provide good frequency agility and allow variable waveforms: low, medium, and high pulse-repetition frequency (LPRF, MPRF, and HPRF, respectively). The latter mode is used for long-range velocity search (VS) with no ranging, while the MPRF is used for track while scan (TWS). “
btw. The author of the article- Michal Fiszer- is a retired Polish AF officer..
mk4 is the general version of C/D gripens as to day, so mayor upgrades from this have been made.
Have you ever wonder why gripen is the first integrator of Meteor? With your bad performance, this would not be a priority..
