This paper introduces briefly MPCSAR principle and its current research situation about the nonequivalent relationship between spatial and time
studies the false target image appearing in the form of pairs of echo when the relationship between platform velocity and PRF fails to be matched.The location formulas for pair of echo in MPCSAR are deduced strictly.Two types of false image(under-sampling false target image and mismatched false target image) are analyzed.A phase compensation method in frequency domain to eliminate these pairs of echo is proposed in the paper also.The conclusions of this paper are verified by simulation.
