US Patent:
5502450, Mar 26, 1996
Filed:
Jul 19, 1994
Appl. No.:
8/276992
Inventors:

US Classification:
342451
Abstract:
A method and system for determining the direction and range to a signal source from a single movable antenna. The direction and range are determined by the simultaneous solution of trigonometric equations which describe triangles including the source and at least two positions assumable by the antenna as apices. The simultaneous equations incorporate the distances from the source to each antenna position as triangle sides and the determination of the relationship between these sides provides for the solution of the equations. The relationship of the triangle sides is determined by detecting periodic symbols occurring in the source signal while the antenna is moved through multiple positions. Actual symbol occurrences corresponding to each antenna position are detected. The expected occurrences at the first antenna position of the symbols actually occurring at the subsequent antenna positions are determined.
