Claims

[Scope of utility model registration request]

a transmitter having a fan-shaped transmitting beam pattern and a receiver having a fan-shaped receiving beam pattern, the transmitter having a fan-shaped transmitting beam pattern and a receiver having a fan-shaped receiving beam pattern, the transmitter being arranged or capable of being arranged such that the fan surfaces of each beam pattern are at right angles to each other; a transmitting circuit that supplies a transmitted signal to the wave receiver; a receiving circuit with a TVG that amplifies and processes the received signal from the receiver; and an indicator that displays the signal from the receiving circuit.
