摘要

辅助阵列方向图与主接收方向图相结合，广泛用于机载和直升机雷达系统的平台运动补偿。提出了一种改进的雷达辅助天线设计方法。在新的准则下推导出任意接收方向图的两种相应的校正方向图，该准则要求阵列的自由度最小，以使所有角度上的杂波残量平均最小，从而利用可能存在的剩余自由度进一步优化校正方向图的副瓣电平。仿真结果表明，平均杂波抵消比接近于最优值，校正模式带来的额外杂波功率最小。

Optimal antenna pattern design for platform motion compensation

Auxiliary array patterns in conjunction with the primary receive pattern are widely used for platform motion compensation in airborne and heliborne radar systems. An improved approach for radar auxiliary antenna design is presented. Two corresponding correction patterns of an arbitrary receive pattern are derived under a new criterion, in which the minimization of the total clutter residue averaged over all angles needs the least degree of freedom for the array, and therefore, with the possibly surplus degrees of freedom, the sidelobe level of the correction pattern can be further optimized. The results of simulation illustrate that the average clutter cancellation ratio approximates the optimal value and the additional clutter power from the correction patterns is minimized.
