一种杂波自适应动态规划检测前跟踪算法
Track-before-detect algorithm with clutter adaptive dynamic programming
摘要
Abstract
The classical dynamic programming track-before-detect (DP-TBD) algorithms based on amplitude accumulation has a very poor performance on detection and tracking under the non-Gaussian clutter environment. However, the DP-TBD algorithm based on likelihood ratio accumulation is difficult to compute accurately the likelihood ratio due to lacking of clutter’s prior information. For this problem, this paper proposes a clutter adaptive DP-TBD algorithm. This algorithm is firstly to implement the test of clutter distribution types of current observed data by employing the method of clutter, and estimate the parameters of the relevant distribution for obtaining the log-likelihood ratio under this distribution of clutter, and next, carry on detection and tracking using the DP-TBD algorithms based on the likelihood ratio accumulation, and finally, perform on simulation analysis by taking examples of clutter models with Weibull distribution and K distribution, respectively. Simulation results show that the performances on detection and tracking of this proposed algorithm are much better than those of the DP-TBD algorithms based on amplitude accumulation.关键词
