本文还提出了一种基于逐次消去思想的互Wigner-Ville分布检测方法

它可以解决强度相差较大的多目标检测问题.仿真实验的结果证明了算法的有效性.

Abstract

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.
