Abstract The observability of radome aberration estimation with line-of-sight (LOS) angle-only measurement is studied in this paper. When missile seeker can only measure LOS angle of target, target state variables are required to be estimated with this measurement for accurate missile guidance. Since LOS angle measurement contains error, caused by radome attached at missile nose and called radome aberration angle, the state estimation performance is degenerated. Thus, the radome aberration effects should be estimated and compensated for accurate target state variable estimation. The radome aberration angle is modeled as the product of radome slope and gimbal angle. The observability of state variables and radome slope estimation is analyzed for the relative dynamics with stationary target model in polar coordinate system. Simulations are conducted to verify the observability conditions obtained in this paper.
