基于动态规划的多目标检测前跟踪算法

Radar Track-Before-Detect Algorithm of Multitarget Based on the Dynamic Programming

本文针对低信杂比条件下的多目标检测与跟踪问题,提出了一种基于动态规划的多目标检测前跟踪算法.该算法能够比较准确地估计搜索空间中潜在的目标数量,并且最佳地分离出每个目标的航迹,从而较好地解决了以往检测前跟踪算法在目标数量未知的条件下容易出现漏警和虚警较多的问题.

For detecting and tracking multitarget under the background of low signal-clutter-ratio （SCR）, a radar track-before-detect （TBD） algorithm of multitarget based on the dynamic pmgramming （DP） is presented.This algorithm can correctively estimate the number of targets in the observed area, and optimally separate the tracks of these targets. Therefore it can solve the problems of missed alarm and much false alarm, which usually arise, when the pervious track-before-detect algorithm are used to detect multitarget on the condition of unknown number of targets.
