摘要
Abstract
The platform's survivability and stealth of penetration can be enhanced via infrared detection by aircraft to detect interceptors.However,infrared detection only provides angle measurement information,which is an incomplete observation for interceptor positioning.It poses significant difficulties for guidance law coefficient identification and motion state estimation.Meanwhile,traditional guidance law identification methods are based on multiple model filtering algorithms,and the identification accuracy is limited by the number of models in the model set.To address the above issues,the observability of guidance law coefficient identification was demonstrated and analyzed based on matrix theory firstly.Secondly,the system state equation and observation equation are established.On this basis,the guidance law coefficients were expanded to filter state components,and the process noise variance was designed.The guidance law coefficients and the motion state were estimated by using the Unscented Kalman Filter.At the same time,the trajectory prediction equation is constructed,and the filtering stable convergence time state was taken as the initial value of trajectory prediction.The trajectory prediction and error propagation analysis were carried out by using Unscented Transformation.The simulation results show that the algorithm proposed can accurately estimate the guidance law coefficient and motion state,and has better universality compared to traditional methods.The trajectory prediction results can provide theoretical support for aircraft to avoid interception and maneuver penetration.关键词
