Electromagnetic fence
摘要:
A system and method can use a transmission line to remotely detect border violations. For example, the transmission line can be configured to use time domain reflectometry to determine when a person and/or object crosses a border. The border can be the border of a country or the perimeter of a facility such as an airport, for example.
