摘要
本文提出了一种宽带毫米波雷达体制下基于高分辨一维距离像的强地物杂波背景中未知速度的高速运动目标检测新算法。该算法的基本思想是：首先放宽虚警率的限制，实现满足检测概率要求的单周期径向积累检测，然后通过多周期中检测结果的特征相关和可移动距离单元的积累去除虚警，以满足给定的虚警概率要求。理论分析和仿真实验表明，该算法可以实现低信杂比、低虚警情况下高的目标检测概率。
A new algorithm for detecting maneuvering target with high but unknown velocity in strong ground clutter background based on one dimension high resolution range profile (HRRP) is presented. The main idea is that the range cells integration detection in one sweep period with very high detection probability is performed regardless of false alarm probability, then the false alarms are removed off by means of features correlation in continuous sweep periods and integration with shifted range profiles. Theoretic analysis and experimental results prove that the algorithm can solve the detection problem with low signal-to-clutter ratio (SCR), low false alarm probability but high detection probability.
