A new electronic countermeasure method to synthetic aperture radar(SAR)
which is called scatter-wave jamming(SWJ)
is discussed in this paper.The characteristics of SWJ and its jamming effect on SAR image are analyzed.It shows in principle that this new jamming method can get better jamming effect than classical jamming techniques.Furthermore
the simulations of SWJ to spaceborne SAR and airborne SAR are executed
