According to the features of airborne SAR moving target echoes
a new SAR moving target detection technique based on cross Wigner-Ville distribution (XWVD) is proposed.Its detection performs on condition that single target and multiple targets exist respectively.The experiment validates that the performance of this new method can detect the signal with very low SNR.It is better than the common method based on Wigner-Ville distribution.To eliminate the effects of cross-terms
according to the idea of elimination one by one
a new detection scheme of XWVD is proposed
which can detect small target embedded in some large targets.The simulation results prove its effectivity.
