中文摘要：
为了明确双线性Chirp变换方法所适用的信号类型，使用Matlab仿真软件对单载频信号和相位编码信号进行仿真试验。仿真从两组带宽不同的滤波器进行。仿真结果表明，双线性Chirp变换对短脉冲具有一定的可重构性，但随着脉宽的增加和带通滤波器通带变窄，其重构性能变差，因此，双线性Chirp变换不能完全适用于单载频信号和相位编码信号。
英文摘要：
To determine which type of signal can be applied to double-linear Chirp transforma- tion, in this paper the Matlab software is employed to test and simulate single carrier signal and phase coded signal. The simulation is proceeded from＇ two different bandwidth filters. The result show that double-linear Chirp transformation has reconstruction ability for short pulse signal, and that with the increasing of the pulse width and the narrowing of the band pass filter, its abili- ty is getting worse. Therefore, double-linear Chirp transformation is completely not suitable to the single carrier signal and phase coded signal.
