Gravity matching result verification method based on carrier displacement

The invention discloses a gravity matching result verification method based on carrier displacement, which is based on the idea of hypothesis testing, utilizes an x2 test method, combines the characteristics of a gravity matching algorithm to design a test algorithm, and utilizes a gravity matching system to observe the difference between a displacement vector and an inertial navigation displacement vector to test the correctness of a matching result. According to the method, under the condition that the inertial navigation initial position error is large, the requirement for identifying the wrong matching result can be met, and the capacity for identifying the wrong matching result under the condition that the prior position information is inaccurate is remarkably improved. 本发明公开了一种基于载体位移的重力匹配结果校验方法，基于假设检验的思想，利用χ2检验法，结合了重力匹配算法特点设计检验算法，利用重力匹配系统观测位移矢量与惯导位移矢量的差异检验匹配结果的正确性。该方法可以在惯导初始位置误差较大的情况下，满足其错误匹配结果识别的要求，在先验位置信息不精确的条件下识别错误匹配结果的能力显著提高。
