Abstract
A system provides a way to determine angle of bearing to a target receiver/transmitter relative to plural beacon stations with rotating directional radiation patterns. The target is “cooperative” in that it transmits a “report” message when the target receives maximum signal strength from a beacon station. Triangulation from multiple beacon transmitter sites can be used to determine the target's position.
Claims16
A method of detecting the position of a cooperative target comprising:
- (a) sweeping the target with a first directional beacon signal emanating from a first beacon position;
- (b) sweeping the target with a second directional beacon signal emanating from a second beacon position different from the first beacon position;
- (c) detecting reports the target emits in response to the first and second swept beacon signals;
- and
- (d) calculating a triangulated position of the target in response to the detected reports.

A method of determining the position of a cooperative target comprising:
- transmitting a first directional beacon signal toward a target;
- detecting a report the target emits in response to the first beacon signal;
- transmitting a second directional beacon signal toward the target;
- detecting a report the target emits in response to the second beacon signal;
- and
- using a processor, calculating a triangulated position of the target in response to timing of the reports.
3 more elements
A system for detecting the position of a cooperative target comprising:
- a first transmitter disposed at a first beacon position, the first transmitter configured to sweep the target with a first directional beacon signal;
- a second transmitter disposed at a second beacon position different from the first beacon position, the second transmitter configured to sweep the target with a second directional beacon signal;
- at least one receiver configured to detect reports the target emits in response to the first and second swept beacon signals;
- and
- at least one processor connected to the at least one receiver, the at least one processor configured to calculate a triangulated position of the target in response to the detected reports.
