Precision Approach Radar PAR-E
The PAR-E Precision Approach Radar is designed for scanning given area, which is intended for the approach and landing control of various aircraft. It supports 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.
The radar is particularly important in situations when the pilot has limited sight (because of fog, rain, etc.). 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. The detected information are displayed on workplace screens and radar information are transferred to remote ATC workplaces. Approach controller consoles can be situated either in the ATM center, the control tower or in the container.
