Abstract:
1. A method for generating a range, bearing, course and speed of contact target motion analysis (TMA) solution based upon a bearing β 1 measured at an initial-time T 1 and a bearing β 2 measured at an end-time T 2 from an observation platform traveling along a single-leg trajectory, a range of said contact being unobservable from said observation platform during said single-leg trajectory except for a best estimation of an initial range R 1 at said initial-time T 1 , comprising: define a two dimensional grid plot whose orthogonal dimensional axis comprise a potential maximum and a minimum of said initial range R within said trial-track sampling space, define a pattern of location of a first plurality of R define a geographic plot which includes the single-leg trajectory of the observation platform and second and third reference lines along bearings β compiling a sequence of bearing measurements Z
