Application of NMTI Method in Wideband Radar Systems
-
摘要: NMTI方法是一种通过雷达回波信号脉间位移来检测运动目标的非相干方法,可用于宽带雷达的动目标检测,有效实现杂波抑制.该文分别以理想矩形和高斯钟形脉冲作为雷达回波信号模型,通过仿真研究,详细讨论了NMTI方法在宽带雷达中的应用。Abstract: NMTI is a noncoherent method to detect moving target through relative range displacement between sequent radar echo signals. It can be used in wideband radar systems for moving target detection and clutter suppression effectively. In this paper, ideal rectangle and Gaussian shape pulse act as radar echo signal model. Through simulation research, application of NMTI method in wideband radar systems is discussed in detail.
