Research on K-L transform based on wavelet transform for anti-chaff-jamming

In modern air-wars, aeroplanes use passive chaff jamming largely, which has already threatened the capability of radars in battlefield. Using netted radar to collect data, the initial echo signals can be achieved. Because of the correlations among waveforms of aeroplane echo signals and irrelevance among chaff echo signals, the netted radar anti-chaff-jamming method of using K-L transform based on wavelet transform is proposed. The simulation results show that the method can antomatically identify the targets and realize anti-chaff-jamming.
