基于多导弹协同目标探测的空间配准算法
Spatial Registration Algorithm Based on Multi-Missiles Cooperative Target Detection
摘要
Abstract
In the technology of multi-missiles cooperative target tracking,an integrated target trajec-tory is generated by fusing the observations from sensors.In ideal environment,sensor biases are consid-ered as zeros.However,due to the existence of biases,the effect of fusion deteriorates.The spatial regis-tration is needed to estimate and compensate the errors.Focused on two types of biases:sensor measure-ment(systemic)biases and attitude(oriented)biases,the paper proposes an improved ECEF-KF method. Firstly,the state models of systemic errors and attitude errors are developed.Secondly,the measurements of missiles are transformed into public(ECEF)system,isolating the motion and rotation of missiles.Third-ly,a Kalman filter based on linear pseudo-measured function is used to estimate the error state.Simula-tions demonstrate that the alignment errors can be exactly estimated and the accuracy of target tracking can be dramatically improved by error compensation.关键词
