一种基于概率的机载红外对地被动定位方法

Airborne Infrared Passive Positioning Method to Ground Based on Probability

测角交叉定位即三角测量法是机载红外设备对地面固定辐射源进行被动定位的常见方法之一,但由于存在测量误差使其在测量定位时精度不高。文中引入概率密度对三角测量法的结果进行分析,确定出最佳定位点,从而可提高测量精度,满足计算要求。

Cross positioning with measure angle, namely trigonometrically survey, is one of the common methods of airborne infrared equipment making a measurement to ground fixed radiation source, since metrical errors have exit, the positioning precision is not high, in this paper, analyze the outcome of trigonometrically survey by introducing density of probability, determine the optimum positioning spot, this method can improve metrical precision and meet the need of calculation.
