Approach radar PAR-E - FIXED

land-basedfor aircraft

The PAR-E precision approach radar provides important support for the approach and landing control of various aircraft, including the emergency landing due to avionics failure. The radar utilizes an active electronic scanning antennas (AESA) both in the azimuth and the elevation which allows operation without mechanical movement of the antennas. The radar meets relevant ICAO standards and follows the NATO Vision document, according to which the PAR technology will be used at least until 2040. The PAR-E Precision Approach Radar is designed for target detection such as aircrafts, ground objects and meteorological formations. The detected information is displayed on workplace screens and radar information is transferred to remote ATC workplaces. The radar is particularly important in situations when the pilot has limited sight (because of fog, rain, etc.) and in emergency landing due to avionics failure. In this situation, the radar has to provide the approach controller with maximum quality radar display complemented by computer evaluation of speed, deviations from glide path/course line, the distance from the previously approaching aircraft, etc. CONFIGURATION The PAR-E Radar design is fully modular and fully duplicated radar solution, including the system of communication with a remote site. The radar construction is fully solid state, including the transmitting circuits. Both azimuth and elevation antennas involve digital T/R modules ensuring their high reliability. The PAR-E Radar system involves the BITE diagnostics to enable fast and accurate identification of a faulty block of the radar system.
