Analysis and Design of a Terminal Homing System Digital Autopilot.

摘要

This report documents the design and performance analysis of a digital autopilot for the therminal Homing Accuracy Demonstration (THAD) program. This autopilot utilizes a digital processor for guidance and stabilization of the T6 missile with the Army Laser Seeker. Under the study guidelines, the autopilot configuration is essentially unchanged, using the laser seeker to generate pitch/yaw proportional navigation signals and two-degrees-of-freedom attitude gyros for pitch/yaw/roll stabilization. The digital autopilot performance is to equal or exceeds that of the existing analog autopilot, the performance criteria being circular error probability (CEP) and the offset of its centroid from the target.
