At last, this paper put forward a recognition method using the parameter of moving target the missle - borne pulsed doppler radar can be achived and the hmm and the analized the limited performance of the method under different circumstance. in chaper 4, this paper analized the temporal chracreristic and spectral chracterisc of hovering helicopter, and then analized the possible methods for detection hovering helicopter and the message that can be achived
第四章中，本文首先分析了懸停直升機回波信號的時域特性和頻域特性，結合彈載高重頻脈沖多普勒雷達的一些具體參數分析了利用彈載高重頻脈沖多普勒雷達對懸停直升機進行檢測的可能途徑和可利用信息。 -
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。 -
By the use of “ radar target backscattering simulation software ” and through many flight mode and research mode experiments with the u. s. - made helicopter ah - 64 as an example, a detailed analysis of helicopter echoes ’ time, frequency domain and time - frequency distribution characteristics is made. finally, according to these features, a tentative plan to detect hovering helicopters is proposed
本文利用專門的電磁模擬軟體，以美製「阿帕奇」直升機為例，詳細分析了直升機雷達回波的時域、頻域和時頻分佈的特性，並根據這些特點提出了雷達探測武裝懸停直升機的初步方案。
