摘　　要：针对雷达多目标检测问题中,并存目标回波能量差异较大导致强目标掩盖弱目标的现象,提出一种基于平行线坐标变换的峰值自寻检测前跟踪算法。通过对比积累后每个量测点所在参数单元内各时刻量测点能量最大值之和,找到能量积累值可达最大的单元,据此形成新的二值积累结果,设置门限进行峰值提取、航迹回溯和航迹修正。仿真结果显示,改进算法对多个目标具有较高的全局检测概率,能够同时检测出不同回波能量的多个目标。In radar detection of multiple targets,the large difference in echo energy of coexisting targets leads to the phenomenon that strong targets cover weak targets.To tackle this problem,a peak self-seeking track before detect(TBD)algorithm based on parallel line coordinate transformation is proposed.By comparing the sum of the maximum energy of measurement point in the parameter unit where each measurement point is located after accumulation,the unit with the maximum energy accumulation value is found,by which a new binary accumulation result is formed.Then peak value extraction,track back-tracking,and track correction are performed with the threshold.The simulation results show that the improved algorithm has a high global detection probability for multiple targets,and can initiate multiple targets with different echo energies.
