Study on Time-delay Inter-pulse Jitter Repeater Jamming Style to Interfere Synthetic Aperture Radar.

Aimed at the contradiction between interference regional coverage and interference power loss in partly coherent jamming styles, a new partly coherent jamming style against synthetic aperture radar (SAR) , time-delay inter-pulse jitter repeater jamming is proposed. In the synthetic aperture time, the inter-pulse time delay of this repeater jamming varies randomly in a small time range. The research shows that this repeater jamming can obtain the whole matched processing gains in range dimension and its SAR imaging output is a similar noise swath, covering a part of fast time domain as well as the whole slow time domain. Thus, it is superior to both noise jamming and other interferences which have dismatched jamming parameters. And it can be implemented easily. The theoretic analysis is given and its performance is verified by simulation. [ABSTRACT FROM AUTHOR]
