Abstract
A false target deceptive jamming method forcountering missile-borne SAR is proposed in this paper, which ison the basis of false target phase template modulation tointercepted missile-borne SAR signal to generate jamming signal.The jammer receiver calculates the phase of missile-borne SARsignal, and modulates the phase of Doppler frequency andbackscattering coefficient data based on range bins, which iscalculated on the basis of the expected position in range directionin advance, to the phase of the missile-borne SAR transmittedsignal. Then, the jamming system calculates and modulates thephase of Doppler frequency in azimuth direction to every rangebin phase of jamming signal and delays corresponding time.Finally, the jammer sums every range bins jamming signal andretransmits it to the missile-borne SAR direction.
