Boundary signal detection
First Claim
1. A boundary signal detection system to distinguish a valid boundary signal for a target region from an extraneous boundary signal for a neighboring region, the boundary signal detection system comprising:
- a vehicle having a propulsion unit, the vehicle carrying a sensor to acquire a candidate boundary signal; and
electronics to;
convert the acquired candidate boundary signal from a time domain to a frequency domain to identify at least one embedded frequency in the candidate boundary signal;
compare the at least one embedded frequency in the candidate boundary signal to at least one predetermined embedded frequency of the valid boundary signal; and
identify the candidate boundary signal as the valid boundary signal based upon the comparison.

Abstract
A boundary signal detection system distinguishes a valid boundary signal for a target region from an extraneous boundary signal for a neighboring region. The system includes electronics that convert the candidate signal from a time domain to a frequency domain to identify at least one embedded frequency in the candidate, that compare the at least one embedded frequency in the candidate signal to at least one predetermined embedded frequency of the valid boundary signal, and that identify the candidate signal as the valid boundary signal based upon the comparison.
