N2 - According to the phased array radar seeker (PARS) in the long-range detection tracking high-speed large maneuvering target exists slow response characteristics, the idea of integrated guidance strategy based on line-of-sight angle rate (LOSAR) feedforward compensation and LOSAR extraction model for two-channel is put forward, which can accelerate the response speed of PARS and keep the target within the beam angle range. In this study, the extended kalman filter (EKF) with a constant command maneuver model is used to estimate feedforward compensation LOSAR and target acceleration. The estimated LOSAR is feedback to the control-loop LOSAR output point of PARS, thereby improving the tracking velocity of the beam control system effectively. The estimated target acceleration is used to calculate the proportional guidance law, thereby improving missile guidance precision. In the simulation, Effect of the integration guidance strategy of PARS on tracking performance with the EKF is investigated. Simulations in icate that the proposed strategy and method are accurate and have certain practical value in engineering.
