FIELD: radio engineering, communication.SUBSTANCE: in electronic warfare, radar stations operate in an environment with highly dense electronic signals. As a result, the radar stations may receive thousands or millions of radar pulses every second. Detecting and sorting out radar pulses emitted from different radars stations is a challenging problem in electronic warfare. The present invention provides a radar pulse detection system that utilises digital channelisation and joint-channel detection techniques to detect and separate radar pulses that are emitted from different radar emitters. The main features of the present invention are: 1) a digital channelisation technique to separate radar pulses from their mixtures; 2) a multi-channel detection technique to detect radar pulses; and 3) a technique to separate overlapped radar pulses.EFFECT: improved method of detecting radar pulses intended for use with digital radar receivers.13 cl, 14 dwg |
