摘要: 结合MIMO雷达多发多收的特点,建立了微波综合脉冲孔径雷达(SIAR)的阵列模型,并提出该阵列的一种实现方案:发射阵采用稀布子阵集,接收阵采用密布子阵的形式.在固定子阵数目和保证阵列孔径的条件下,利用联合选择和两倍交叉的修正遗传算法对这种双基地SIAR平面阵的子阵位置进行优化,以降低方向图的旁瓣电平.仿真结果表明该方法提高了搜索速度,合成阵列方向图最大峰值旁瓣电平可达到-31.1dB,满足工程需要.

Abstract: On the basis of array model of the Multiple-Input Multiple-Output (MIMO) radar, a universal array model of the Synthetic Impulse and Aperture Radar (SIAR) is constructed and a realization sheme for microwave SIAR with a thinned subarray set for the transmitted array and a dense subarray set for the received array is proposed. Then a modified genetic algorithm (GA) with combined selection and double cross is employed in the optimization of the subarray position of bistatic SIAR antenna arrays to decrease the pattern’s sidelobe level with a fixed subarray number and a constant array aperture. Simulation results show that the modified GA raises the convergence velocity greatly with the maximum peak relative sidelobe level (RSLL) reaching -31.1dB, which meets the requirement of the project.
