基于视频积累的距离扩展目标检测

正确提取目标强散射中心,并对强散射中心的能量进行有效的积累,是高分辨率雷达距离扩展目标检测的关键.本文先根据最大信噪比原则估计出目标窗口,然后在此窗口中利用门限检测方法提取目标强散射中心,最后利用广义似然比方法推导了自适应单扫频周期径向积检测器.仿真结果表明比文献1]提出的SSD-GLRT检测器的性能有较大的改善.

Range Extension Target Detection Based on Video Frequency Accumulation

Extracting main scatter center of the target correctly and accumulating the energy of the main scatter center are the key to the high resolution radar range extension target detection. The target window on basis of maximum signal to noise ratio principle is estimated irstly, then the target main scatter center is extracted in this window by using threshold deteetion method, finally the adaptive mono frequency sweep period radial product detector is derived by using generalized likelihood ratio method. The simulation resuh shows that the performance is improved greater than that of the SSD-GLRT detector proposed in Reference1].
