摘要
在考虑WGS-84椭球地球模型条件下,推导了单星多普勒测频无源定位精度,分析了速度误差、站址误差、测频误差、目标高程误差、时间间隔等因素对定位精度的影响,结论对单星无源定位系统定位精度指标的论证与分析具有借鉴意义。
Considering the condition of WGS-84 ellipsoid earth model, this paper deduces the passive location accuracy of single satellite Doppler frequency measurement, analyzes the influence of fac- tors such as velocity error, station address error, frequency measurement error, target height error and time interval, etc. on location precision. The conclusion is useful for the argumentation and a- nalysis of location precision indexes in single satellite passive location system.
