This appendix develops exact and approximate relationships between parameters in target location and clutter Doppler spread equations. The parameters are shown, using the North-referenced coordinate system. Because exact relationships are required, the isorange contour must be an ellipse, rather than the tangent approximation (perpendicular to the bistatic angle bisector). Initially, this requirement would seem to be intimidating, but the results are surprisingly tractable when ellipse eccentricity, e, is used in the development.
