摘要
针对提高雷达回波信号捕获率的要求 ,对雷达高度表视频回波信号高速采集系统提出了改进方案 .对采集系统在实际工作中可能会受到的持续强干扰的情形 ,通过动态调整门限的方法实现捕捉中的恒虚警概率 ,并根据回波自身的特点提出多帧近似的模糊处理方法 ,从而提高了捕获率 .
Two technical schemes to improve the ability to locate and catch the echoes are put forward. In the case of continuous strong noise, constant false alarming rate (CFAR) can be realized by dynamically adjusting the contrasting level. A method of using former frame of data to approximate to the actual situation is also given. The help of these two measures can obtain higher capture rate.
