One issue with underwater sensors is how to efficiently transfer large amounts of data collected by the node to an interrogating platform such as an underwater vehicle. It is often impractical to make a physical connection between the node and the ve

雷达发射线性调频信号，载频10GHz，线性调频信号带宽10MHz，脉宽5us，采样率自设，两目标距离雷达5000米和5020米 （1）模拟两个目标的回波，并进行脉冲压缩（匹配滤波），验证脉冲压缩对改善雷达距离分辨力的作用 （2）调整两个目标的间距从1米到20米，观察结果得出结论。-Radar transmitting chirp signal, carrier frequency 10GHz, chirp signal bandwidth of 10MHz, pulse 5us, sam
