作者介绍了一种用于测量海洋波高和潮位的Ku波段雷达探测系统。该系统可同时探测波高和潮位 ,其测量精度优于传统测量设备 ,并可以岸站或船载使用。文中对该系统探测回波的基带信号信道数据处理 ,特别就多信道中信号串扰和大动态背景的抗干扰检测方法进行了论述 ,并给出了系统的测试结果和误差分析。 The author introduces a Ku-band radar detection system for measuring ocean wave height and tide level. The system can simultaneously detect wave height and tide, the measurement accuracy is better than the traditional measuring equipment, and can be used onshore or on board. In this paper, we deal with the baseband signal channel data of echo detection in this system, especially the interference detection of signal crosstalk in multi-channel and large dynamic background, and give the test results and error analysis of the system.
