A STUDY OF FILTERING TECHNIQUES APPLIED TO THE DART ANGULAR RATE SENSOR.

Abstract

The DART is a transducer that converts a two dimensional angular rate vector into a phase and amplitude modulated sinusoidal voltage. The DART output statistics indicate that a valid model for the output is the signal plus additive noise that is independent of the signal, Gaussian, and white in a frequency band centered on the signal. A zero-suppression filter as well as least-mean-square error linear and nonlinear filters are designed and tested. The best filtering technique applied to the output of a particular model of the DART, decreased the lowest rate detected from 21 degrees/second to 0.002 degrees/second. (Author)
