| 摘 要： | 探讨了在大片分布均匀的气象杂波环境下,如何建立动态杂波图和轮廓杂波图,并利用这两种立体杂波图产生有无杂波的判断标志,从而降低虚警概率及提高雷达的检测性能,并在Matlab软件下对算法进行了仿真分析。着重分析了气象杂波边缘问题的处理,并给出了整个硬件电路的结构框架图,最后通过FPGA实现了整个杂波图。

| Abstract: | The present paper discusses how to establish and exploit volume clutter map to reduce the false alarm probability and improve the detection probability of radar under the uniformity of weather clutter environment.The performance of algorithm is simulated under Matlab.The effect of weather clutter edge is analysed,and the architecture of the hardware is also provided,finally the clutter map is realized by FPGA. |
