分数阶傅里叶变换在Chirp调制信号中的应用
Application of Fractional Fourier Transform in Chirp Modulation Signal
摘要
Abstract
An algorithm which can directly disperse a continuous FRFT was analyzed by the use of the discrete FRFT algorithm definition and the principle of the dimension normalization. Meanwhile,the shortcomings of the processing chirp signal were improved by using this algorithm,and the algorithm calculation was simplified. The demodulation of chirp signal was studied based on FRFT,and the optimal fractional fourier order of chirp signal energy concentration were also determined.关键词
