On a Third Order Linear Predictor-Corrector Digital Filter

Abstract

A third order linear predictor-corrector digital filter with parameters w1, w2, and w3 is introduced and discussed in this paper. Four particular ones, with different choices of w1, w2, and w3, have been or are being used at White Sands Missile Range (WSMR) of the US Army. In particular, McCool's QD filter and Sheperd's third order parabolic spline filter were devised at WSMR for missile trajectory smoothing, reconstruction, and differentiation. Stability conditions for these filters are derived and discussed. In addition, the filter equations are uncoupled so that design criteria can be obtained.
