【摘要】：空时插值方法通过对地面杂波空时导向矢量进行插值变换,能够有效地降低机载前视阵雷达地面杂波的距离依赖性,改善空时自适应处理器的杂波抑制性能。然而,当机载雷达接收通道存在阵元误差时,该方法对接收的数据处理失效。针对该问题,提出一种稳健的空时插值方法,该方法在杂波空时导向矢量周围选取约束导向矢量,然后进行插值变换,补偿地杂波距离依赖性。仿真结果表明,当机载雷达接收通道存在阵元误差时,该方法能够有效地降低接收的地杂波数据的距离依赖性,提高空时自适应处理器的杂波抑制性能。
[Abstract]:The space time interpolation method can effectively reduce the range dependence of ground clutter and improve the clutter suppression performance of the air time adaptive processor by interpolating the ground clutter space-time guidance vector. However, when the airborne radar receiving channel has the array element error, the method fails to deal with the received data processing. In order to solve this problem, a robust space-time interpolation method is proposed. This method selects the constraint vector around the direction vector of the clutter time, and then interpolates the distance dependence of the clutter. The simulation results show that the method can effectively reduce the received ground clutter number when there is an array element error in the airborne radar receiving channel. According to the distance dependence, the clutter suppression performance of space-time adaptive processors is improved.
