Claims

[Scope of utility model registration request]

An antenna of a mobile body that transmits and receives CW waves, a mobile body that communicates while moving using transmitted and received signals from the antenna, a plurality of directional antennas that transmit and receive CW waves from the mobile body and directs them to the mobile body, A plurality of drive units that move each directional antenna, a control unit that controls the drive units, a transmission/reception unit that transmits and receives communication signals to and from the directional antenna, a communication unit that generates and receives communication signals, and a control unit. a storage unit that stores the driving angle signal from the transmitter and the reception signal level from the transmitting/receiving unit, a reception maximum level detection unit that detects the antenna angle at which the reception level is maximum from the data in the storage unit, and the reception signal level and the communication compliance level. After receiving the CW waves from the moving object and directing the multiple directional antennas to the angle where the reception level is maximum, the CW wave from the moving object is The directional antenna remains stationary at that pointing position while the receiving level is high enough to communicate with the object, and if communication becomes impossible, the directional antenna resumes repeating the pointing operation and captures the moving object. Passive tracking communication that avoids fluctuations in reception quality and mechanical wear of antennas, and arbitrarily changes the orientation of multiple antennas when a moving object comes close to communicating in a stopped state.
