Abstract :
A new method for passive ranging based on the principle of triangulation is considered. The proposed orthogonal dual baseline scheme eliminates the well known “geometric dilution” effect, inherent in single baseline methods. The performance of each of the two orthogonal baselines depends on target orientation. A general expression for the maximum triangulation range consistent with limitations in minimum tolerance precision in range estimation is derived. Limitations in the dual baseline model due to physical limitations created by the geometrically assessed optical horizon are also considered
