Abstract:

Taking the intercepting missile seeker’s measurement system as a subsystem of interception systems and focusing on miss distance and interception energy cost, the effect of interception seeker measurement error on interception efficiency is investigated. A proportional navigation interception system model is set up. In this system, input is an intercepting missile measurement error and outputs are miss distance and interception energy. Both the miss distance and the energy cost caused by seeker’s measurement error are simulated in this system. By numerical statistics, the quantized relationships between the interceptor seeker’s measurement error, the miss distance and energy cost are exhibited that provides technology reference to guidance system design or missile penetration for the intercepting missile.
