Modernized Ground-Controlled Approach (GCA) system RSP-10MA is intended to ensure flight safety of aircraft and helicopters within terminal airspace, obtain positional information and guide aircraft to a safe landing in normal and adverse weather conditions. RSP-10MA combines primary and secondary radars, and Precision Approach Radar (PAR).
As a result of modernization the radar’s detection performance has been efficiently improved. Modernized radar features automatic tracking capability as well as data receiving from other radar sensors. Data can be transferred over a variety of communication channels.
Primary channel of RSP-10MA operates in L-band (ICAO), secondary channel uses standard frequencies for RBS (interrogation – 1030 MHz, response – 1090 MHz) and Eastern UVD (interrogation – 1030 MHz, response – 740 MHz). Primary and secondary channels work on a common antenna. Precision Approach Radar performs vertical and glide path guidance and operates in X-band.
Transmitter and receiver of PSR/SSR feature solid-state components only. Transmitters have modular design and provide ‘soft-failure’ redundancy: failure of individual module leads to partial performance degradation. Antenna system of PSR/SSR is equipped with a new asynchronous motor drive assembly controlled by frequency inverter.
Radar includes PSR/SSR operator workstation and PAR operator workstation equipped with air situation displays and radio control panels.
All air situations are automatically recorded with playback capability in passive and interactive modes. RSP-10MA is powered from two independent power supplies: from three-phase industrial mains (380V, 50 Hz) and from diesel power generators.
RSP-10MA features efficient protection against pulse interference and active jamming. Level of interference is continuously monitored and graphically represented to operator. Jamming protection is achieved through expansion of the dynamic range of the signal processor and capability of electronic frequency agility. Passive interference is rejected through digital adaptive MTI and generation of clutter map.
