A Three Dimensional Augmented Spherical Tracking Filter for Maneuvering Air Targets.

Abstract

This report discusses the design and implementation of the adaptive three dimensional maneuvering target tracking filter in spherical coordinates. All filter performance statistics concerning intercept range, probability of kill, cumulative probability of kill, S1G3D, etc. were obtained from the statistical analysis program called GUSS. Since GUSS performs its analysis in rectangular coordinates while the filter filters in spherical coordinates, two additional sets of subroutines were required to act as buffers between GUSS and the filter. The first of these sets converted the GUSS supplied three dimensional target position data from rectangular to spherical coordinates. The second set, which was much larger than the first, converted the filtered estimates of target position and velocity in each of the 3 spherical coordinate directions into their equivalent values in rectangular coordinates for subsequent processing by GUSS.
