  1. The reseach work focused on the time delay estimation of the common practical radar singnals, including harmonics signal, chirp signal, polynomial phase signal, and phase - shift keying signal. the new algorithm for different radar signals are deduced in detail respectively, and simulation results are presented. the results proved that the new method is efficient for time delay and some other parameters estimation

    正弦信號、線性調頻信號、多項式相位信號、相位編碼信號是雷達信號中常用的幾種信號,對這幾種信號的研究是雷達信號處理中非常重要的內容,也是實際工程的需要。因此,本文選擇上述幾種信號作為研究對象,對這幾種信號的時延估計演算法進行了建模和理論推導,給出了時延估計演算法的具體表達式,並進行了計算機模擬。
