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 section that stores the received signal level and angular position signal from the transmitting/receiving section, a time width detection section that detects a signal exceeding a certain time width from the data in the storage section, and a maximum reception level from the data that has passed through the time width detection section. a reception maximum level detection section that detects the angular position of the time;
Consists of a comparison section that compares the received signal level and the tracking establishment level, and a gate circuit that gates the maximum reception angle, receives the CW wave from the moving object, and sets the directivity to the angle where the reception level is maximum. After pointing the antenna and establishing tracking of the moving object, turn on the transmission, and if tracking is not established even after a certain period of time, point the directional antenna at the angle of the second received signal level, A passive tracking communication device characterized by starting communication to a moving object.
