在发射端发射大时宽、带宽信号，以提高信号的速度测量精度和速度分辨力，而在接收端，将宽脉冲信号压缩为窄脉冲，以提高雷达对目标的距离分辨精度和距离分辨力。(In order to improve the speed measurement accuracy and speed resolution of the signal at the transmitter, the wide pulse signal is compressed into a narrow pulse at the receiving end to improve the range resolution and range resolution of the radar.)

说明：  协作通信中DF模式。程序中也只仿了一个中继时的编码转发协作形式。(cooperative diversity DF)

用于对基于GOLD码的串行捕获算法，可以自定义信噪比，待捕获信号参数，代码分成搜索跟踪和捕获两部分，其中搜索的步长等参数也可以自定义，代码中acquiresignal.m部分为最终捕获相位展示的主程序。(For the serial acquisition algorithm based on GOLD code, we can customize the signal-to-noise ratio and the parameters of the signal to be captured. The code is divided into search part and capture part, The parameters such as search step can also be customized. Acquiresignal.m part is the main progress to output the results of the capture of phase.)
