摘要 文中介绍检测啁啾信号的新技术-分数傅里叶变换。它可以有效的对噪声环境下啁啾信号进行检测。最后用仿真结果证明该方法的有效性。 A new technique for detection of chirps-Fractional Fourier Transform is presented, which can complete the detection of chirps containing multiple signals with various characteristics effectively in a noisy environment. At last, Simulation results are presented.
