韦布尔分布海杂波的建模与FPGA实现

Modeling and FPGA Implementation of Sea Clutter Based on Weibull Distribution

雷达回波模拟器在雷达设计中是不可缺少的一部分,对于雷达系统的设计发挥着重要作用,而海杂波模拟又是雷达回波模拟器设计中的关键一环。文章选取杂波建模中常用的韦布尔分布模型进行了分析,给出了其ZNML产生方法,并在FPGA实现,最后给出了实现的结果并与理论值比较,达到了很好的效果,可应用于雷达回波模拟器的设计中。

A radar echo simulator is essential in radar design, which plays an important role in design of the radar system; and the sea clutter simulation is also a key link in design radar echo simulator. The Weibull distribution model common used in clutter modeling is selected and analyzed, and its ZNML generating method is given, and it is implemented in FPGA. And finally, the implemented result is given and compared with theoretical value, the resuits prove that this model achieves a perfect effect and can be applied in design of the radar echo simulator.
