摘要
检测概率是雷达效能评估的重要指标之一.通过对单滤波器组间的跨越损失分析,可知当目标落在滤波器组交叠处会明显降低检测概率.本文设计增加一组滤波器,覆盖单组滤波器交叠区域,降低单滤波器组间的跨越损失,从而在整个频率范围内都具有较好的检测性能,并给出仿真过程和工程试验数据,具有良好的工程实现效果.
Detection probability is one of the important indices of effectiveness evaluation of radar. The analysis of spanning loss between filters shows that when the target falls in the overlapping part of filter groups, the detection proba-bility will be significantly reduced. In this paper, the design of another filter group, covering the single filter banks over-lapping area, reduces the spanning loss between the single filter groups, so as to have better detection performance in whole frequency range. The simulation process and engineering test data are given, which have a good engineering effect.
