通過對加速度模糊函數(shù)的形態(tài)分析也指明了針對線性調(diào)頻信號的二次相位匹配處理( chirp - fourier變換)在應(yīng)用到制導(dǎo)雷達(dá)信號處理中所存在的缺陷。
In this paper , the concept of acceleration ambiguity function ( aaf ) and acceleration resolution is put forward for the first time . using aaf , the effects of target ' s relative acceleration on several outputs of a linear - phase matched filter are analyzed , such as the output signal - noise - ratio loss , the doppler resolution , the constraint on optimal accumulative time ( opt ) and their tolerable limits
論文首次提出并研究了加速度模糊函數(shù)和加速度分辨力的有關(guān)概念，并以加速度模糊函數(shù)為分析工具，詳細(xì)討論了加速度對線性相位匹配濾波器的輸出信噪比的損失程度、對多卜勒頻率分辨能力的影響程度、對最優(yōu)相參積累時間的約束關(guān)系以及線性相位匹配濾波器輸出受加速度影響的容限等問題。
