Best management of FM waveform by a missile-borne pulsed Doppler radar during high-manoeuvring target tracking in strong clutter environment

摘要

Referring to the application of missile-borne pulsed Doppler radars, the use of a radiofrequency HPRF-FM seeker, having a monopulse tracking processing, is considered in scenarios with a low altitude flying high-manoeuvring target. During target tracking the seeker has to solve the situations when the clutter signal occupies the target frequency positions and tracking can be lost. The algorithm that is presented shows how to dynamically choose an optimum FM factor, so to reduce clutter disturbing effects and to maintain a stable target tracking.
