Claims

[Scope of utility model registration request]

A tracking receiver that tracks a moving object by receiving radio waves from a moving object moving from a long distance to a short distance or from a short distance to a long distance while emitting radio waves, uses an array antenna consisting of multiple antenna elements. , a beam control section consisting of a switch that switches the signals received by the individual antenna elements, a monopulse comparator that monopulse synthesizes the received signals output from the beam control section, and a monopulse comparator that receives the monopulse synthesized signal and performs appropriate a receiver that amplifies the signal to a predetermined level using an AGC voltage after converting it to a suitable intermediate frequency; and an AGC that outputs an AGC voltage proportional to the strength of the received signal in order to perform automatic control in the receiver. circuit, a detector that detects the output signal of the receiver and outputs a tracking error angle signal, and a contact point of the switch of the beam control section when the AGC voltage proportional to the strength of the received signal exceeds a predetermined value. a control unit that outputs a beam control signal for widening the antenna beam width, lowering the antenna gain, and correcting changes in tracking error voltage due to changes in the antenna beam width; and a beam control signal from the control unit. A tracking reception device comprising: an amplifier that amplifies a tracking error angle signal to a predetermined tracking error voltage; and an antenna control unit that drives the array antenna in the direction of the moving object using the tracking error voltage from the amplifier. Device.
