摘要
本文通过对加装在713雷达上的地物杂波抑制器试验结果分析,指出:经“抑制”处理后,能快速,准确地将气象回波从地物杂波中分开来。采用分级衰减方法对比观测,气象回波损失约5分贝。 采用地物杂波图后,可以改善地物杂波抑制器性能,增大了抑制器在天气雷达组网拼图中的应用前景。
The field experimental results of the ground clutter rejector equipped on the weather radar 713 are analysed in this paper.The recognition of the meteorological echos in the clutter areas is fast and accurate after the rejecting processing. Using the contrast observation of a step-by-step attenuation, the loss of the meteorological echo in the clutter processing is about 5 db.
After adding the clutter map the performance of the clutter rejector may be improved, the application vista of the clutter rejector in radar observation network will be increased.
