The PS-05/A is a pulse-doppler, multimode search radar which is used in the JAS 39 Gripen fighter aircraft. The PS-05/A functions in the 8-10 GHz band and has 1 kW energy output (> 10 kW maximum output). It is composed of four parts: 1) travelling wave tube power amplifier/transmitter unit; 2) a 23 kg signal/data processor; 3) a 32 kg software-controlled exciter/receiver unit; 4) a 25 kg antenna/platform assembly. All four parts can be replaced in 30 minutes. The radar is capable of detecting, locating, identifying and automatically tracking multiple targets in the upper and lower spheres, on the ground and sea or in the air, in all weather conditions.
The D80 signal/data processor employs a software written in Pascal and incorporates a built-in test routine. To provide the required operational flexibility, low, medium and high Pulse Repetition Frequency (PRF) functions are used together with a range of waveform modes which include Air-to-Ground Ranging (AGR)A ground target ranging mode. The Doppler Beam Sharpening (DBS) is a synthetic aperture mode which employs Doppler processing and is used for high-resolution ground mapping with high angular coverage obtained via continuous antenna scanning.
