中文摘要：

针对目标雷达截面积（radar cross-section，RCS）空间起伏，不易于常规雷达进行长时间积累检测的问题，结合正交频分复用（orthogonal frequency-division multiplexing，OFDM）波形与分布式多输入多输出（multi-ple input multiple-output，MIMO）雷达的特点，提出了一种基于分布式 OFDM-MIMO 雷达的非相参积累目标检测方法。该方法使获得的多路回波信号短时间内非相参并行处理，削弱了长时间积累、复杂的相位补偿以及 RCS快起伏对检测性能的影响，有效实现了多个目标的积累和检测。仿真结果证实了提出方法的有效性。

英文摘要：

It is difficult for the traditional radar to detect targets with radar cross-section （RCS）fluctuation via the long-time coherent integration.Combining the characteristics of multiple-input multiple-output （MIMO） radar and orthogonal frequency-division multiplexing （OFDM）waveform,an incoherent integration detection method is proposed using distributed OFDM-MIMO radar.The parallel incoherent processing of the multi-channel echo in a short time is exploited to weaken the effect caused by the long-time integration,the complex phase compensation and the fast RCS fluctuation.Then,the multi-target integration and detection are realized ef-fectively.Simulation results verify the superiority of the detection method using the distributed OFDM-MIMO radar.
