| 摘 要： | 无人机高精度高度保持装置,通常采用误差相对较小的无线电高度表来作为测量高度或高度差的传感器。无线电高度表在海面上测高时,由于海杂波以及自身噪声等随机干扰信号的影响,会产生较大误差。为消除或减小海杂波以及自身噪声等随机干扰信号对无线电高度表的影响,需要对无线电高度表输出信号进行必要的处理。本文着重论述采用维纳滤波法最优估计技术来设计提高无线电高度表抗干扰的措施方法。

| Abstract: | Radio altimeter is commonly used for measuring altitude and altitude difference of UVA altitude rest.In order to eliminate or reduce the effect of random jamming signal on radio altimeter,the output signals must be processed.So the optimum estimate of Wiener filter is proposed for enhancing the antijamming ability of radio altimeter. |
