Besides designing and selecting waveforms, in order to acquire high time bandwidthproduct, it is the major practical method to increase the bandwidth of the signal with limited time duration.
除了对波形本身的设计和选择，设法增大有限时宽信号的带宽，是实际获得大时带积脉压信号的主要手段。

Pulse compression technique is widely used in modem radar systems. Large time duration-bandwidthproduct signals are used in pluse compression technique to improve the resolution in range domain.
