S波段两坐标雷达反气象的一种方法

The Design of Adverse Weather in S Band 2-D Radar

S波段雷达通常会受到较强的气象杂波干扰 ,尤其在沿海地区还会有特殊的气旋。本文介绍了一种用剩余杂波图技术自适应调整恒虚警门限 ,用来抑制 MTD处理后的气象杂波剩余。以及采用剩余杂波图技术 ,根据多种不同凹口 MTI滤波器的杂波剩余 ,自动选择杂波单元内的最佳 MTI滤波器 。

In S band operation, radar is typically interfered by the heavy weather clutter, especially in littoral regions where exists a specific mesocyclone. This paper introduces an approach to restrain the weather clutter residue after MTD processing that is the residual clutter pattern and adaptive threshold adjustment technology. Through employing the residual clutter pattern technology, we can automatically select out the optimal MTI filter in the clutter element according to the clutter residual corresponding with several different notch MTI filters, and enhance the improvement factor of system.
