<FONT face=Verdana>Using the idea of micro motion modulation for reference

a novel active jamming method is proposed for Synthetic Aperture Radar (SAR). Several key jamming parameters are determined

the jamming image result is analyzed

an implementation procedure based on Digital Radio Frequency Memory

well as the influence of reconnaissance errors on jamming performance

is put forward. Furthermore

simulation experiments have been done based on the raw data. The result shows that

this jamming signal is processed coherently in the range direction and partially coherently in the azimuth direction

which can produce multiple false targets in the azimuth direction. As an effective and sound jamming

this method

along with multiple equipped or developing jamming equipments

can enhance the defense and survivability for important targets.
