Claims

[Scope of utility model registration request]

In the tracking radar device, a transmitter section that creates a transmission wave, a transmission/reception switching circuit that switches and transmits the transmission wave and the reception wave, an antenna section that emits the transmission wave into the atmosphere and receives the radio wave in the atmosphere, and the above-mentioned. A receiver converts the high-frequency signal received by the antenna into a video signal, and the video signal from the receiver allows distance tracking by constantly keeping the distance difference between the distance to the tracking target and the distance displayed by the tracking radar device to a minimum. an angle tracking unit that performs angle tracking by always keeping the angular difference between the turning and elevation angles of the tracked target position and the turning and elevation angles of the tracking radar device to a minimum; an antenna drive section that drives the antenna section based on an angular error signal of the roller;
a measurement calculation section that calculates the speed of the target being tracked from the amount of change in the distance signal from the distance tracking section and the amount of change in the angle signal from the antenna drive section; and a target speed signal from the measurement calculation section. a shooting calculation unit that predicts the future position of the target and calculates the firing angle;
an AGC voltage determination circuit that determines the posture of a target based on a change in an automatic gain control voltage (AGC voltage) for correcting the strength of a received signal of the receiving section;
It consists of a gate circuit that outputs only the video signal of the target that is found to be in close proximity by the GC voltage discrimination circuit, and after firing, it is shut off and the tracking radar device will detect if the bullet passes near the target by mistake.
A tracking radar device characterized in that the above-mentioned gate circuit prevents a problem in which a video of a bullet from a distance is tracked by a video of a bullet.
