中文摘要：

针对传统动态规划检测前跟踪（DP-TBD）算法对高速微弱目标的检测和跟踪问题,利用一种结合正交频分调制（OFDM）波形和分布式多输入多输出（MIMO）雷达的分布式OFDM-MIMO相控阵雷达,提出基于该雷达的TBD方法.MIMO雷达的全向辐射特性能够大大降低TBD单帧回波获取时间,另外,分布式雷达的空间部署可以削弱目标雷达截面积（RCS）起伏.仿真结果表明：本文方法检测和跟踪性能良好,是一种有效检测高速微弱目标的方法.

英文摘要：

Aimed at the detecting and tracking problem of high‐speed weak target via traditional dy‐namic programming track‐before‐detect （DP‐TBD） algorithm ,a TBD method was proposed based on a novel radar which combines distributed multiple‐input and multiple‐output （MIMO） phased radar with orthogonal frequency‐division multiplexing （OFDM ） waveform , i .e ., distributed OFDM‐MIMO phased radar .Omnidirectional radiation property of M IM O radar can reduce single frame echo obtai‐ning period greatly in TBD processing .Besides ,space deployment can smooth the target′s radar cross‐section （RCS） fluctuation .The simulation results demonstrate the feasibility of this method .
