摘要 针对机载脉冲多普勒雷达检测弱目标困难,提出一种改进的动态规划方法.在动态规划算法中引入多级幅值累加判决门限,在循环递归过程中丢弃一部分目标轨迹,减少了算法计算量.经实测数据验证,该方法在强杂波背景下能较好地检测出低信噪比运动目标。 An improved dynamic programming （DP） method was presented for the weak target detection of airborne pulse-Doppler radar, in which the decision making Of multi-stage multi-thresholds were used, some redundant target paths were rejected and the corresponding computation was reduced. The real data verifies that the method can be used for detecting the moving target under the low SNR, and improving the detection performance of radar weak target for airborne pulse-Doppler radars.
