摘要：
研究了存在系统误差下被动传感器测向交叉定位系统中的最优交会角问题。考虑实际应用中传感器不可避免地存在系统误差,传感器的测量误差设定为非零均值高斯分布,在不同的准则下,计算了两部传感器测量误差不同情况下的最优交会角,讨论了系统误差和测角精度对最优交会角的影响,得到的相关结论在指导多传感器的优化配置和提高定位精度方面具有一定的实际意义。
Abstract:
The optimal cut angle is studied in passive sensor triangulation when system errors exist. Since system errors cannot be avoided in practical application, the measure errors of the sensor can be assumed as Guass distribution with non-zero average. Then the optimal angles with different measure errors of two sensors are calculated under different criteria, and the influence of the system errors and measure precision on the optimal cut angle is discussed. The obtained results can be used to reference the deployment of passive sensors and improve the location accuracy.
