    基於自動最佳擬合曲線的波速測定和目標定位方法可以比較準確地計算出波速，計算出目標位置，優點是運算量小，缺點是容易受到雜波干擾的影響。
  3. At one time complex structure and area of weariness crack ( including whole suspension hollow axis of swivel, half suspension adopted axletree, substituting holistic grinding steel wheels for wheel - hoop compounded wheels, different wheel - axletree structure of different locomotives, different transmission chamfer machining step of axletresses and driven traction gear etc. ) centralizing make wave clutter and repeat to disturb recognition of real fault wave

    同時，由於全懸掛空心軸、半懸掛抱軸承等復雜結構車軸的使用和整體碾鋼輪陸續替代輪箍組裝式車輪，各型機車輪軸結構不同，車軸加工臺階和過渡圓角不同，從動牽引齒輪與車軸採用過盈裝配等，在這些結構復雜且疲勞裂紋產生集中的區域，探傷時極易發生波形交織和重復，難以識別真正缺陷波。
  4. Combined with the key project of the preliminary research of national defence science and technology, the target recognition system for millimeter wave initiative homing guidance, a systematic study on the signal processing method based on the background of millimeter mave ( mmw ) missle - borne pulsed doppler radar is performed. it include specifically the detction and the recognition of the moving target and hovering helicopter under strong clutter background

    本文結合國防科技重點預研項目「毫米波主動尋的制導目標識別」 ，針對脈沖多普勒體制雷達導引頭的應用背景，對基於彈載高重頻脈沖多普勒體制雷達的信號處理方法進行了較深入的研究。主要研究內容包括對雜波背景中的機動目標以及對懸停直升機的檢測和識別方法。
  5. The land clutter is useless signals for target detection caused by land terrain. the multipath effect is some kind of interference which is caused by wave reflection on terrain. the diffraction effect is the phenomenon of wave propagation into shadow region

    地雜波是由地面散射引起的對目標探測無用的信號;多路徑是由電磁波在地面反射所引起的干涉;衍射則是電波繞射傳播到遮蔽區的現象。
