The feasibility of blanket jamming against space-borne SAR is analyzed. Through calculating the power of blanket jamming, it is concluded that the coherentpulses can jam space-borne SAR.
The probability of multi-photon pulse in weak coherent source can be decreased by canceling two photon pulses to improve the security distance.
