PAR-E – PRECISION APPROACH RADAR The PAR-E precision approach radar is designed to support the approach and landing control of various aircraft, including the emergency landing due to avionics failure. The radar utilizes an active electronic scanning antenna (AESA) both in the azimuth and the elevation level. The radar meets ICAO recommendations and standards. Configuration of the PAR-E radar is characterized with following properties:  The radar construction is fully solid state, including the transmitting circuits. Both azimuth and elevation antenna involve digital T/R modules ensuring its high reliability. Radar configuration The PAR-E radar consists following basic parts: resolution consists in creating radar structure, which flexibly adapts customer’s requirements and needs. The radar can be transported by standard vehicles for ISO ferry containers. PAR-E is fully duplicated radar, including the system of communication with a remote site. The MTBCF value is 13,400 hrs minimum. The “Radar Equipment cabin” container includes a cabinet for embedding the spare parts kit, which allows to keep the MTTR parameter below 30 minutes. Antenna system (AESA) Radar Equipment cabin Power supply unit – Diesel generator, UPS unit Fire fighting system Security electronic system Philosophy of PAR-E radar design is based on creating modular solution with units as independent as possible. The reason of such In its basic configuration, the radar is independent from the public supply network; the configuration involves a power station. In case of a stationary site, the radar configuration is complemented with the UPS unit to ensure the radar operation during the shorttime supply voltage failure.  The PAR-E radar system involves the BITE diagnostics to enable fast and accurate identification of a faul
