Modular Digital Missile Guidance, Phase II

B. A. Hall / F. J. Langley / L. J. Casey / T. J. Cullinane / R. J. Fitzgerald

This report presents the results of the second phase of a study to investigate the feasibility of a modular digital guidance system for Navy air-to-air missile applications. The studies involved the analysis of functions for digital implementation in all classes of air-to-air missiles and the derivation of computer requirements in terms of throughput memory, architectural features, modularity and compatible software characteristics. The functions of: target seeker head control, estimation, guidance and autopilot were addressed in the first study phase and those of seeker signal processing, fuzing, telemetry, test and flight phase/mode control were analyzed in the second study phase reported herein. In addition, simulation analyses of estimation, guidance and autopilot algorithms were performed to determine performance improvement as a function of complexity. In summary, the studies have shown that modular digital guidance and control is both feasible and effective in improving missile performance and flexibility to counteract changing threat situations and advancing technology.
