Research on Omnidirectional Interception Guidance Law with Impact Angle Constraint
To address the problem of impact angle constraint in the design of space interception guidance law, the paper puts forward the impact Angle-Constraint Omnidirectional True-Proportional Navigation (AC-OTPN) guidance law and solves the technical problem of high-speed target interception with terminal impact angle constraint.Based on OTPN, AC-OTPN is added with time-varying bias angle velocity.It also real-timely solves time-varying bias angle rate, hoping to get expected terminal impact angle.AC-OTPN can self-adaptively choose head-on and head-pursuit interception patterns according to the motion relationship of target and interceptor.It has large capture region and high accuracy of impact angle.By adjusting the terminal impact angle, AC-OTPN can increase the impact effectiveness.Interceptors with less mass and smaller volume can also have the same kill ability.AC-OTPN provides technical support for the miniaturization design of interceptors and their ability to carry more sub-interceptors.
