摘要

为解决低信杂比下雷达检测前跟踪技术存在末级检测门限设置困难和动态规划算法对运动目标跟踪能力弱的问题

本文首先分析了两级检测门限的雷达检测前跟踪算法自身特点.在瑞利杂波条件下

对经过动态优化后的信号进行杂波置信检验和航迹检测和校正.该算法末级检测门限设置简单并且提高了跟踪概率.仿真验证了新方法的有效性.

Abstract

In low signal-to-clutter ratio

in order to solve the problem of the terminal threshold setting and poor capability in tracking with the moving target based on dynamic programming (DP) algorithm

the characteristic with two-steps detection thresholds in radar track-before-detect(TBD)is analysed.In the background of Rayleigh clutter

signals after optimizing are confidence tested and trajectory calibrated.This algorithm makes terminal threshold setting easy and improves the track probability. Simulations testify the validity of the new algorithm.
