设计了一类基于VMSR的改进型恒虚警检测器,给出了检测器的检测结构框图,同时描述了该类检测器的检测模型并给出了相应的检测概率表达式。该类检测器通过VR删除算法自适应删除杂波背景中的干扰样本,并将剩余样本按照不同操作得到杂波背景功率估计,提高了复杂杂波背景下检测器的精确性及鲁棒性。通过与典型VMSR-CFAR检测器的仿真对比实验,验证了该类检测器的检测性能。
A kind of improved constant false alarm detector based on VMSR is designed. The detection structure diagram of the detector is given. At the same time, the detection model of this kind of detector is described and the corresponding detection probability expression is given. This kind of detector adaptively removes the interference samples from the clutter background by using the VR deletion algorithm and obtains the clutter background power estimation according to the remaining samples according to different operations so as to improve the accuracy and robustness of the detector under the complex clutter background. By comparing with the typical VMSR-CFAR detector, the detection performance of this kind of detector is verified.
