摘要
通过预估初距 ,将距离、方位滤波法应用于纯方位单目标定位问题 ,利用二乘滤波原理建立了多方位 -距离滤波法应用于观测器方位序列估计目标运动参数的数学模型 ,给出并严格证明了方位与初距的变化规律 ,为建立快速。
With giving a firstrange,bearingonly target locating is studied by multibe arings and onerange filter. A mathematical model for estimating motionparame ter of target based on bearing series is given by multibearings and onerang e filter, and the change relation between bearings and range is discussed and pr oved.Finally the theory foundation for establishing rapid and practical visual model is provided.
