Abstract

Conventional practice in single-sensor passive track is to fit azimuth-elevation object observations with polynomials in the early stages of track initialization. At least three and usually more observations are fitted to quadratic polynomials before they are accepted for testing with a six dimensional model. This paper develops an alternative to these polynomials based on closed-form solutions of the trajectories in angle-space. This paper is applicable when both the sensor and target are in free fall. The approach relies on a flat-earth assumption to achieve the solutions. Experimental comparisons are made with the polynomial fit method.
