摘要
在高动态下传统双基集中式多输入多输出(MIMO)雷达收发波束形成方法实现存在复杂度高的问题。针对这一问题,提出了一种基于频域划分和部分匹配滤波(PMF)的双基集中式MIMO雷达收发波束形成方法。所提方法通过先对多普勒频率在频域进行划分,然后在各小多普勒频率通道内利用基于PMF的波束形成方法进行数据处理,从而降低了工程实现的复杂度。仿真结果表明,所提方法能够在保证波束形成性能的条件下有效降低工程实现的复杂度,便于工程应用。
The conventional receive-and-transmit beamforming method for the bistatic colocated muhiple input multiple output （MIMO） radar under large dynamics generally has a high complexity.In view of this problem,an improved beamforming method based on frequency-domain splitting and partial matched filter （PMF） is proposed for the bistatie colocated MIMO radar.The proposed beam- forming method splits the Doppler frequency within the frequency-domain firstly, and then processes the data by the beamforming method based on PMF in every split small Doppler frequency channel, so the implementation complexity can be reduced.The simulation results show that the proposed method can reduce the implementation complexity while ensuring the beamforming performance and suit the engineering application.
