摘　　要：对于线性调频脉冲信号 ,设置一个称为湖明函数的幅度加权函数 ,以便进一步增加它的输出信号的主副瓣比 ,多普勒频率范围也拓宽许多。描述经湖明函数加权的线性调频信号的各基本性能 。The mainlobe peak to sidelobe peak ratio of a linear FM output signal can be increased by setting an amplitude weight function called Huming function, and the Doppler shift spectrum also can be broadened. In this paper, the basic characteristics of a linear FM signal weighted by Huming function are described and compared to those of FM signal weighted by Hamming function and Taylor function are.
