System for interception, direction finding and localisation of broadband radio transmissions

摘要

The system has an antenna network (1) switchable to the receiver (2). The system has a wide bandwidth. An analysis section (3) produces a Fast Fourier Transform and provides detection and angular information. The outputs are examined in a processing circuit (4) and different modes can be commanded from a command unit (5). The overall architecture allows different execution instructions in different digital words, allowing real time FFT processing, antenna detection and angular position processing and providing output positional and detection information.
