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. The device consists of a comparator section that gates the maximum reception angle, and a gate circuit that gates the maximum reception angle.The device receives CW waves from a moving object and directs the directional antenna to the angle that maximizes the reception level, allowing tracking of the moving object. A passive tracking communication device characterized in that after establishment, transmission is turned on and communication to a mobile object is started.
