Abstract
A new method jamming against Waveform Agile SAR/GMTI (Ground Moving Target Indication) is proposed, which is called the intermittent sampling motion scatter wave jamming. This jamming can form multi-false vivid targets scene taking the real moving targets’ all scattering information. The intermittent sampling repeater can also repeat in the waveform agile SAR current pulses. As a clever jamming mode, this jamming may realize electronic counter measure (ECM) against wave- form agile SAR. Detailed discussions about the jamming performance are given. The processing output of the jamming is derived theoretically. The superiority of this jamming is analyzed in theory. The theoretical feasibility and validity are proved by simulation experiments.
Highlights
Synthetic aperture radar (SAR) is an all weather imaging radar, and SAR Ground Moving Target Indication (GMTI) capability is an important means for strategic reconnaissance and battlefield surveillance systems, which makes it a sever threat to important military targets
The new method jamming against Waveform Agile SAR/GMTI is necessary for protecting these important military targets
The Motion jammer can repeat waveform agile SAR subsection signal in the currently pulse with little delay by the intermittent sampling repeating. It might takes advantage of the intermittent sampling scatter wave jamming against waveform agile SAR GMTI
Summary
Synthetic aperture radar (SAR) is an all weather imaging radar, and SAR Ground Moving Target Indication (GMTI) capability is an important means for strategic reconnaissance and battlefield surveillance systems, which makes it a sever threat to important military targets.

The Motion jammer can repeat waveform agile SAR subsection signal in the currently pulse with little delay by the intermittent sampling repeating. It might takes advantage of the intermittent sampling scatter wave jamming against waveform agile SAR GMTI. The model of intermittent sampling motion scatter wave jamming is established for waveform agile SAR\GMTI.
