Transformations for Range Instrument Coordinates and Their Tracking Space Singularity Regions
Abstract
The non-linear transformations relating rectangular coordinates to range instrumentation coordinates for conventional radar, phased array radar, AME (Angle Measuring Equipment) etc., are considered. The transformations are linearly related through Jacobian matrices at the derivative (rate) and first differential or discrete difference (residuals or linearizing about a nominal) level. State variables near the singularity regions of these matrices can cause numerical computer problems for the unwary analyst.
