随着复杂的空间环境、更繁杂的飞行器种类以及更先进的隐身技术的发展,使得在复杂环境中的弱目标检测成了一个亟待解决的重要问题。针对传统雷达检测算法在处理弱目标时,面临着检测算法效果的瓶颈问题,采用检测前跟踪算法作为一种新的算法框架,则比传统算法具有更好的性能。文中在主流的基于动态规划的检测前跟踪算法基础上加以改进,引入航迹剪枝流程,解决动态规划带来的虚警尾过多的问题,使该算法更具现实工程应用意义。
The more complicated space environment, more various aircrafts and more advanced stealth technology, bring the problem of weak target detection under complicated environment forward to the radar technology research. The traditional radar detection algorithms confront severe bottleneck in weak target scenarios, while a new algorithm scheme:track-before-detect has better performance under such circumstances. This paper proposes an improvement of the existent dynamic programming based TBD algorithm introducing double tracking pruning, which can solve the basic problem of false alarming increase caused by dynamic programming itself. This improvement can make the algorithm more practical and realizable in engineering.
