| 摘 要： | 讨论了平滑Wigner Ville分布 (WVD)在动目标检测 (MTD)中的应用。传统的MTD是通过Doppler滤波器组来实现的 ,但由于Doppler滤波器组的旁瓣电平往往较高 ,从而限制了对目标的检测能力。给出的基于平滑WVD的MTD克服了传统方法的缺点。对该方法进行了理论分析和计算机仿真。理论分析和仿真结果均验证了此方法的有效性

| Abstract: | This paper discusses the application of the smoothed Wigner Ville distribution(SWVD) in moving target detection(MTD). Traditionally, MTD is realized by Doppler filter bank. Since the sidelobe levels of Doppler filter bank are usually high, the target detection ability is limited in the conventional MTD. The method based on the SWVD presented in this paper overcomes the shortcoming of the traditional method. Its validity is proven by both theoretical analyses and computer simulation. |
