阐述了海浪杂波特点,结合频率捷变雷达(FAR)的组成和工作原理,讨论了频率捷变技术、信号积累检测技术、自适应门限单元平均和单元选大参量恒虚警检测技术等在雷达抗海杂波设计中的实际应用,给出了频率捷变雷达的海浪杂波和目标回波频域特性,开展了一些验证试验,并对雷达和路检波和航控电压等试验数据进行了分析,结果表明频率捷变雷达的抗海浪杂波干扰性能满足要求。
The characteristics of the sea clutter are described. Combining with the composition and working principle of Frequency Agility Radar (FAR), frequency agile technique, signal accumulation detection technique, adaptive threshold unit averaging and unit selected constant constant false alarm detection technique are discussed Radar anti-sea clutter design of the practical application, given frequency agile radar wave clutter and the target echo frequency domain characteristics, to carry out a number of validation tests, and radar and road detection and pilot voltage test data The results show that the anti-clutter jamming performance of frequency agile radars meets the requirements.
