Claims

[Scope of utility model registration request]

An antenna that transmits and receives CW waves, a mobile object that communicates while moving by transmitting and receiving signals from the antenna, a directional antenna that transmits and receives CW waves from the mobile object and directs it to the mobile object, and a drive that moves the directional antenna. a control unit that controls the driving unit; a transmitting/receiving unit that transmits and receives communication signals to and from the directional antenna;
a communication section that generates and receives communication signals;
A storage unit that stores the received signal level and angular position signal from the transmitting/receiving unit, a maximum reception level detection unit that detects the angular position at the maximum reception level from the data in the storage unit, and a comparison between the reception signal level and the tracking establishment level. It consists of a comparison unit that gates the maximum reception angle, a gate circuit that gates the maximum reception angle, and a transmission control unit that selects whether to start transmitting communication radio waves to a mobile object automatically or manually. After receiving the CW wave, orienting the directional antenna to the angle where the reception level is maximum, and establishing tracking of the moving object, automatically or manually turn on the transmission and start communication with the moving object. A communication device with passive tracking.
