| 摘 要： | 多输入多输出（multiple-input multiple-output, MIMO）雷达与传统相控阵雷达相比，其最大优势在于由天线孔径空间卷积带来的更高的角度分辨力。将多部X波段相控阵雷达组成共置天线的分布式相参MIMO雷达可以实现更窄的波束宽度，但随之而来的是严重的栅副瓣问题。以降低MIMO雷达稀布阵旁瓣电平为目标，对共置天线的分布式相参MIMO雷达阵地布置进行优化。仿真试验结果显示粒子群算法应用到该最大最小问题是有效和稳健的。

| Abstract: | Compared with conventional phased array radar, the most distinct advantage of multiple-input multiple-output (MIMO) radar is that it has higher resolution due to the space convolution of the antenna aperture. Several X-band phased array radars can be constructed to form a distributed coherent MIMO radar with collocated antennas for narrower beam, but the trouble accompanying with this is the serious grating lobe. The paper optimizes the antenna array geometry of the distributed coherent MIMO radar with collocated antennas for the aim of reducing the grating lobe of the plane sparse arrays of MIMO radar. The simulation results show that the particle swarm optimization is effective and robust in the min-max design. |
