| 摘 要： | 为了实现火炮快速定向,文中以卫星信号为参照,给出了在一定基线下,利用天线的"和差方向图"进行炮口定向的基本原理。论述了自适应滤波在"差信号"最小点计算过程中的应用。仿真结果表明,自适应滤波可有效抑制"差信号"中的噪声,从而可以利用"和差方向图"实现较为准确的快速定向。

| Abstract: | The basic principle of artillery orientation determining on the base of signal of Satellite positioning system is described.On the base of antenna pattern of sum signal and difference signal,a new method is proposed to realize artillery quickly orientation.Application of adaptive filter in the minimum calculation of the antenna pattern of difference signal is discussed.The simulate result shows that,adaptive filter can suppress noise in antenna pattern of difference signal.So,the artillery quickly orientati... |
