Radar seeker system for use with air launched missile, derives correction signal from estimated value of target azimuth sightline rate signal representing deviation of missile from preset flight path

摘要

A controller derives a measure of target angle off the missile roll axis using radar signals such that the missile is steered based on the target angle. The bias in the system, produces a discrepancy between the true and measured values of the angle. A correction signal is incorporated with the measured value of the angle such that the correction signal is derived from an estimated value of target azimuth sightline rate signal representing deviation of the missile from predetermined flight path.
