Abstract

The invention provides a data source generating method for passive direction finding location. The method aims at high cost of satellite passive direction finding location, is based on the theory of passive direction finding location, and includes initial setup, earth satellite kinematics environment recursion, observation data generation and other links. The invention has the characteristics of flexible parameter setting, high computing speed, and high accuracy of output observed quantity. Practical engineering problems in the process of on-satellite location algorithm design, namely, difficult calibration and low calibration efficiency, are solved. A large number of reliable data sources can be provided for location algorithm verification. A location result obtained by the method can be used as the basis for checking the accuracy of a direction finding location algorithm.

Description

technical field [0001] The invention relates to the technical field of satellite passive positioning, in particular to a data source generation method for passive direction finding and positioning. Background technique [0002] Satellite passive positioning can usually be divided into single-satellite system and multi-satellite system. The single-satellite system adopts the instantaneous direction finding method to locate the target. The basic schemes mainly include the amplitude method, the phase method and the time difference method. No matter which direction finding principle is used, its purpose is to obtain the direction of the target in the satellite body coordinate system. Among them, the phase method is mature in technology, easy to implement in engineering, and easy to be adopted by engineering. [0003] At present, the verification method of the direction finding and positioning algorithm is mainly to set the simulation time, satellite orbit and attitude paramete...
