Claims (1)

[Scope of utility model registration request] In a shooting tracking radar device, a transmitter unit that creates a transmission wave, a transmission/reception switching circuit that switches and transmits the transmission wave and reception wave, and an antenna unit that emits the transmission wave into the atmosphere and receives radio waves in the atmosphere. , a receiving section that converts the high-frequency signal received by the antenna section into a video signal, and a video signal from the receiving section that constantly keeps the difference between the distance to the tracking target and the distance display of the tracking radar device to a minimum, thereby determining the distance. A distance tracking section that performs tracking; an angle tracking section that performs angle tracking by always keeping the difference between the turning and elevation angles of the tracking target and the turning and elevation angles of the antenna section of the tracking radar device; and the angle tracking section. an antenna drive unit that moves the antenna unit based on an angular error signal; an metric calculation unit that calculates the speed of the tracked target based on a change in the distance signal from the distance tracking unit and a change in the angle signal from the angle tracking unit; A shooting calculation section that predicts the future position of the target from the target speed signal from the above-mentioned measurement calculation section and calculates the firing angle of the gun; A Doppler signal detection unit that compares the Doppler frequency calculated from the calculated target speed and outputs a gate pulse only when they are equal, and outputs the received signal from the receiving unit only when a pulse is output from the Doppler signal detection unit. When the bullet passes near the target after firing, the gate circuit cuts off the video of the bullet to prevent the problem of accidentally tracking the video of the bullet. A tracking radar device for shooting.
