为进一步满足未来现代化战争中预警机多功能、一体化和小平台的设计要求,提出了机载MIMO雷达基于对地/海监视任务模式下的最优阵列合成结构设计方法,并给出了相应的最优化问题的解法.最后,对该算法进行仿真,结果表明该算法实现了机载MIMO雷达在最小的阵元负荷下最好的阵元利用率,当最小可检测速度小于10 m/s时,改善因子明显高于均匀发射波形结构,对低慢速目标的检测性能优势更为明显.

To further satisfy the design requests of early-warning aircraft for multi-purpose,integrated and the small platform in future modernization war,an optimal array synthetic structure design method for airborne Multiple Input Multiple Output(MIMO)radar is proposed,which works under the mode of Ground/Sea Moving Target Indi-cator(GMTI). At the same time,a resolvent for optimal problem is proposed. Simulation of the proposed algorithm shows that the method can realize the best sensor utilization ratio under the least sensor burden,and when the Minimum Detectable Velocity(MDV)is smaller than 10 m/s,the improvement factor is higher than that of the even launch profile structure obviously and is more obvious to the low and slow target examination performance.
