Cognitive Radar Waveform Diversity for Anti-Passive False Target Jamming in an Active Radar Seeker

Based on the principle of cognitive radar, this paper proposes a waveform diversity method to resolve the passive false target jamming. Different signal leads to different one-dimensional scattering centers of the ship and passive false target, the presented method focuses on measuring the target and passive false target jamming one-dimensional scattering centers Distinction Degree (DD). Using the Distinction Degree as adaptive waveform criterion and according to the criterion selected the optimal waveform for anti-passive false target jamming. Finally, according to the recognition rate, the method verified the optimal waveform.
