代码说明:

雷达因可以检测目标的距离、速度和角度的性能在现代社会中得到了广泛的应用,不仅是军事方面,在现实生活中也可以见到各种雷达的应用,而现代雷达对于测距精度有很高的要求,而测距精度与信号脉宽是一对不可以调和的矛盾,所以我们需要根据不同的应用设计不同的脉冲宽度,而相位编码由于其自身的特点,其信号有很好的相关性能,在雷达发射信号中得到了广泛的应用,而其中巴克码是一种很常见的二相编码信号,这次毕业设计的主要内容是尝试通过matlab仿真设计一个基于巴克码发射信号的雷达系统,通过模拟产生对7位和13位巴克码信号的产生,然后根据发射信号的回波信号我们对其进行脉冲压缩,然后比较7位和13位巴克码信号产生的脉冲压
