摘要
天线阵面与平台共形可有效利用平台的空间,口径达到最大,由于天线方向性系数的改变,地面杂波的分布与常规平面阵不同。本文对圆柱共形阵的地面杂波进行了仿真,给出了机载运动平台和气球载准静止平台地面杂波的分布,并对系统滤波器设计提出了建议。
Conformal antenna array and platform can effectively use the platform aperture.It is easy to achieve the maximum array aperture.Due to the change of antenna directivity coefficient,the ground clutter distribution is different from that of plane array.The ground clutter distribution of a conformal cylindrical array of airborne moving platform and balloon-borne quasi-stationary platform is simulated in this paper.Some suggestions on the design of system filter are put forward.
