一种多普勒雷达修正逻辑起始算法

针对一类具有多普勒量测的航迹起始问题,首先推导了目标任意三个时刻的斜距量测与多普勒量测乘积线性组合的统计特性,进而提出了一种修正逻辑起始算法.该算法通过在传统逻辑起始算法的航迹扩展阶段加入点迹关联的假设检验环节,来降低虚假航迹的数目.仿真结果表明,该算法的航迹起始概率与传统逻辑起始算法相当,而其虚假航迹数远远小于传统逻辑起始算法,并且运算量略有降低.

A Doppler Radar Modified Logic Track Initiation Algorithm

To solve the problem of track initiation with Doppler measurements, this paper primarily deduces the statistic characteristics of the linear combination of the products of range and Doppler measurements at three arbitrary time instances, based on which, a modified logic track initiation algorithm is proposed. The proposed algorithm decreases the number of false tracks by adding the module of Hypothesis testing into the stage of track extension in traditional Logic-Based initiation method. Simulation results show that the proposed algorithm produces much less false tracks and slightly less computation load than traditional Logic-Based initiation method, while keeping the nearly equal track detection probability to the traditional Logic-Based initiation method.
