A Method of Anti-Nonsynchronous Short Pulse Jamming Based on Waveform Entropy

In the condition of complex electromagnetic environment and multifarious methods activate jamming, anti-jamming approach has been highlighted. Anti-jamming method based on waveform entropy is used to counter nonsynchronous short pulse jamming because its low compute complexity easy implementation. This paper analyzes performance, obtain decision threshold value by taking use kernel function, exhibit influence radar system. The equivalent signal-to-noise ratio improved at least 12.2 dB compared with normal detector.
