Normalized miss distance analysis of single-lag optimal guidance law with radome effectsaturation and fifth-order control system

This paper deals with miss distance analysis of single-lag Optimal Guidance Law (OGL) using linearized equations of motion in normalized form. The radome refraction error, acceleration limit, constant target acceleration, and arbitrary-order binomial guidance and control system are considered in the formulation. In addition, body rate feedback is utilized in the OGL formulation as a well-known classical compensation method of radome eect for proportional navigation guidance. The numerical solution of normalized equations produces normalized miss distance curves, which are useful tools for guidance designer for analysis and design of guidance parameters for an allowable miss distance and acceleration limit. Moreover, a modied rst-order guidance scheme, based on an analytical stability analysis and normalized miss distance curves, is presented for reducing the achievable miss distance
