Improvement of AN/TPQ-27 Filter and Control Techniques.

Abstract

A modified linear Kalman filter with deterministic forcing is used to improve the tracking capabilities of the Marine Corps AN/TPQ-27 remote tactical aircraft guidance system. Both sixth and ninth order filters are developed and used with the Precision and Coarse Guidance simulation programs. A technique for overcoming the effects of autopilot bias is presented and tested through simulation. Precision Guidance control is modified to utilize angle error and angle error rate to generate corrective commands. Significant improvement in aircraft state estimation, bombing accuracy, and overall system response is shown. The Coarse Guidance algorithms and simulation program are nearly completely new and perform aircraft guidance to the bombing run with more than adequate precision under simulated conditions.
