Effect of Instrument Siting and Coordinate Selection on GDOP in Target Tracking,

Abstract:

Simultaneous direct measurements taken in elevation, azimuth and range for independent instrumentation sources, when aggregated and reduced can often yield sensible estimates. However, strong aberrations and inconsistencies in the estimates derived from data reduction have been known to occur. Two particular factors are investigated in order to partially explain theoretically these elusive deviations and to establish some cause and effect relationship. The first set of factors relates to the relative geometric siting of the instruments as well as the type of measurements recorded. Typical measurements which would be conducive to such aberrations are discussed. The second set of factors relates to the selection of a frame of reference for aximuthal measurement. It is shown that coordinate selection can play for certain types of measurements a significant role in multiplying the GDOP by severalfold from a rationally established minimum basis. Author
