Compared to the theory signal, the chirp produced by DDS under large bandwidth, may have frequency distortion due to the limited chirp-rate.
受限于DDS芯片的调频转换速率，在大带宽下，DDS产生的线性调频信号相比理论信号可能存在频率失真。
The transmission spectrum bandwidth increases with the chirp parameter, while the transmission decreases, which leads to worse filter feature;
②随着啁啾系数增大，透射谱带宽增大，透射率降低，滤波性能变坏；
Chirp signal is a kind of pulse-compressed signal with large time-bandwidth products achieved through linear frequency modulation. It has high resolution in range because of its great bandwidth.
线性调频信号是通过线性频率调制获得大的时宽带宽积的一种脉冲压缩信号，具有大的带宽，因此有高的距离分辨力。
