The representation of aaf and its resolution not only enriches relative theory of radar signal processing and is instructive in radar parameter design and performance analysis , but also provides a practical method to quantitatively evaluate the acceleration effects on signal processing 加速度模糊函數及其分辨力的概念不僅豐富了雷達信號理論的有關內容，為雷達參數設計和性能分析提供了一定的指導意義；而且也為實際工作中定量地衡量加速度對信號處理的影響提供了分析手段。 |

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和加速度分辨力的有關概念，并以加速度模糊函數為分析工具，詳細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、對最優相參積累時間的約束關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。 |

Through the detailed analysis of the aaf , the defection of using chirp - fourier transform in guidance radar signal processing is pointed out 通過對加速度模糊函數的形態分析也指明了針對線性調頻信號的二次相位匹配處理( chirp - fourier變換)在應用到制導雷達信號處理中所存在的缺陷。 |
