Claims

[Scope of utility model registration request]

In a radar device that automatically tracks a target by emitting radio waves and receiving reflected waves from the target, a transmitter that generates radio waves to detect the target and a trigger generation circuit that generates the repetition frequency of the transmitter. , a gate signal generation circuit that generates a gate signal necessary for distance tracking of the target based on the signal from the trigger generator, a transmit/receive switch that switches between transmitting radio waves and receiving radio waves, and a transmitting/receiving switch that emits the transmitting radio waves and moves away from the target. an antenna that receives reflected radio waves from the antenna, a reference signal generator that generates a reference signal, a mixer that mixes the reference signal and the radio waves received from the antenna and converts it into an intermediate frequency, and amplifies the output from the mixer. an intermediate frequency amplifier, a detector that converts the output from the intermediate frequency amplifier into a video signal, an automatic gain adjustment circuit that adjusts the output from the intermediate frequency amplifier to a constant amplitude, and a gate from the gate signal generation circuit. a distance tracking circuit capable of tracking a target by comparing signals with the target; an angular error detection circuit detecting an angular error between the center direction of the antenna beam and the target position based on the output from the intermediate frequency amplifier; An antenna drive circuit that directs the antenna in a target direction by amplifying the output from the angular error detection circuit, and an antenna drive circuit that controls the output from the reference signal generator in synchronization with a gate signal generated from the gate signal generation circuit.
