Online Target Estimation and Cooperative Guidance Method for Anti-radiation Missile in Ground Attack
摘要
Abstract
Passive radar seeker used in anti-radiation missile can only acquire target azimuth information without relative range information,making it difficult to precisely determine target position and velocity,thereby limiting strike effectiveness.In addition,although multi-missile coordinated strike represents the mainstream operational approach for enhancing enemy radar destruction efficiency,it faces the challenges such as channel coupling in three-dimensional coordinated guidance.To address these issues,an extended Kalman filter(EKF)algorithm was used to estimate targets using high-precision position and velocity data from a single missile.Distributed measurement data from multiple missiles were fused through a centralized EKF framework to achieve cooperative multi-missile state estimation.The estimation accuracy of the EKF was compared across three seeker configurations:purely passive,purely active,and active-passive hybrid.In cooperative guidance design,a time-cooperative guidance law with attack angle constraints was investigated.By designing cooperative and tracking planes,the three-dimensional guidance law was transformed into a two-dimensional problem,thereby decoupling the pitch and yaw channels.A closed-loop"online estimation-real-time guidance"system was established,achieving simultaneous estimation and guidance to eliminate error accumulation.Simulation results demonstrate that the proposed EKF based multi-missile fusion method reduces target position estimation error by 50％and significantly enhances convergence speed.The guidance law enables effective coordinated strikes against radar targets,providing technical support for the design of the guidance law for anti-radiation missile.关键词
