OREANDA-NEWS. Specialists of Ryazan State Instrument-Making Enterprise (RSIME) [1]became the winners of the Aircraft Manufacturers of the Year[2] Contest in the nomination titled "Achievements in the Development of Aircraft and Components (the Design Bureau of the year)". RSIME design team presented the prototype of the APAR interrogation radar for the next-generation fighter jets. It was installed and tested on the modern fighter jet Su-35S.

The development of airborne radar systems for the new aircraft significantly increases the number of technical requirements not only to primary means of detection, but also to secondary radar systems, which perform a crucial task of identifying the nationality of the detected targets. And first of all, it is about the aircraft radio interrogator.

For the first time in Russia, RSIME has developed an APAR unified airborne interrogation radar 4283MP, installed at the front-edge consoles of the fighter jet wings.

The product utilizes digital methods of signal formation and processing, which significantly increases the probability of target identification in challenging target and jamming conditions, as well as the accuracy of target location in space.

The APAR technology allows for considerable increase of the energy potential and of the range, resolution, and work areas at the corners of the recognition of objects, detected by the onboard radar equipment.

The APAR transmitter-receiver modules utilize semiconductor power amplifiers, which do not require forced cooling and thereby significantly simplify their installation on the object.

However, the autonomous installation of the interrogator antenna system allows to perform the tasks of target identification, in conjunction with the key work of the onboard radar, and to execute the commands from other onboard detection systems.

Thanks to the new technical solutions, radar interrogator 4283MP, which was developed and manufactured by the Ryazan plant, can operate in Russian and international systems of recognition alike.

Last year, RSIME experts actively participated in the testing of the airborne radar interrogator 4283MP on the Su-35S.

Proven technical solutions and algorithms for signal processing of functional software formed the basis for the design of the new airborne interrogation radars that are being developed by RSIME specialists for the Mi-28 helicopter and the fifth-generation fighter T-50.
