A sequential probability ratio test (SPRT) is introduced as a track management (TM) mechanism for the joint probabilistic data association (JPDA) multitarget tracking algorithm. The SPRT is based on an approximate target likelihood ratio that is derived from the JPDA event and association probabilities. SPRT-based TM functions are defined and compared to the joint integrated probabilistic data association (JIPDA) algorithm, including a discussion of parameter tuning for both approaches. Simulation experiments are reported for multiple closely spaced constant-velocity targets over a range of values for detection probability and clutter density. The SPRT-based algorithm achieves performance similar to JIPDA for this data, but with fewer TM parameters and a more straightforward parameter-tuning process.

联合概率数据关联的顺序目标存在统计

引入顺序概率比测试（SPRT）作为联合概率数据关联（JPDA）多目标跟踪算法的跟踪管理（TM）机制。SPRT基于从JPDA事件和关联概率得出的近似目标似然比。定义了基于SPRT的TM函数，并将其与联合集成概率数据关联（JIPDA）算法进行比较，包括两种方法的参数调整讨论。据报道，在一定的检测概率和杂波密度值范围内，对多个紧密间隔的恒速目标进行了仿真实验。基于SPRT的算法可针对此数据实现与JIPDA相似的性能，但具有更少的TM参数和更直接的参数调整过程。
