NMTI方法在寬帶雷達系統(tǒng)中的應用
Application of NMTI Method in Wideband Radar Systems

摘要: NMTI方法是一種通過雷達回波信號脈間位移來檢測運動目標的非相干方法,可用于寬帶雷達的動目標檢測,有效實現(xiàn)雜波抑制.該文分別以理想矩形和高斯鐘形脈沖作為雷達回波信號模型,通過仿真研究,詳細討論了NMTI方法在寬帶雷達中的應用。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.
