Abstract :
32-channels passive imaging system is developed in the frequency range 33...38 GHz. The system contains multibeams quasi-optical scanning antenna with an array of low noise direct detection receivers. New type of scanning mechanism on the base of asynchronous three-phase motor is used. The software-hardware complex has been created to control scanning mechanism and to process the receiving information. Simultaneous receiving of signals from different parts of scene allows to form a good quality image on the monitor screen in 3 seconds. The developed imaging system can be used to provide navigation on the ground or at sea, especially at short distances where surface radar clutter is high, for remote sensing in space and air investigations, for all-weather surveillance, for objects discovering, and many other commercial applications.
