高频地波雷达目标的识别检测方法

Pattern-based Approach of Target Detection in HFGW Radar

由于高频地波雷达的检测背景十分复杂 ,目标信噪比特征不明显 ,使得常规恒虚警检测不能很好地得到背景和目标的估计。针对高频雷达中目标和噪声在三维谱图中的不同特征 ,应用模式分析策略 ,提出了基于识别的混合检测结构的检测器 (PDPA方法 ) 。

Because of the complex and various background under high frequency environment, the CFAR detectors can not estimate the noise and the target properly so as to get poor performance According to the difference of target and noise in 3D spectrum image, the pattern based approach is addressed After the peak detection, the pattern analysis is constructed normally and rationality The good performance is obtained on some real time data set
