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

摘要

For detecting and tracking multitarget under the background of low SCR, a radar track-before-detect algorithm of multitarget based on the dynamic programming is presented. This algorithm can exactly estimate the number of targets in the observed region, and optimally separate the tracks of these targets. Therefore it can solve the problems of missed alarms and false alarms, which usually arise, when the pervious track-before-detect algorithm are used to detect multitarget with unknown number of targets.
