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 transmitting/receiving section that transmits and receives communication signals using the transmitting/receiving RF signals from the monopulse comparator attached to the directional antenna, a communication section that generates and receives communication signals, and a received sum signal and a received difference signal from the transmitting and receiving section. It is composed of an error detection section that detects an angular error signal, a control section that controls the drive section using the angular error signal, and an EL limit circuit that limits the EL drive command signal from the control section. When receiving waves and controlling the directional antenna using the angular error signal,
A passive tracking communication device characterized in that it performs stable communication with a moving object by restricting the EL angle to point toward the ground or sea surface.
