雷达微弱目标检测前跟踪技术研究综述

An overview on track-before-detect technique for radar weak targets

战场环境的改变、武器系统的发展和隐身技术的应用,使得现代雷达系统对目标的检测和跟踪面临很大挑战,检测前跟踪技术是解决微弱目标检测和跟踪问题的一种有效方法。首先介绍了检测前跟踪技术的基本原理,然后重点综述了雷达微弱目标检测前跟踪算法的发展历程和研究现状,包括三维匹配滤波、动态规划、Hough变换、粒子滤波等检测前跟踪算法,并对常用的几种算法进行了对比分析,最后结合目前研究动态提出了雷达微弱目标检测前跟踪技术需要重点关注的问题和未来发展趋势。

The change of battlefield environment,the development of weapon systems and the application of stealth technique bring a great challenge to modern radar systems in terms of target detection and tracking. Track-before-detect（ TBD） technique is an effective approach to resolve the detection and tracking issue of weak targets. The fundamental of the TBD technique is introduced firstly. Afterwards,an overview on the development history and status quo of the TBD algorithms for weak targets is presented emphatically,including the 3D matched filtering,the dynamic programming,the Hough transform and the particle filter. The commonly-used TBD algorithms are compared and analyzed. Finally,some key issues and future development trends of the TBD technique are analyzed based on the progress of the existing TBD research.
