Claims (1)

[Scope of utility model registration request] A shooting tracking radar device includes a transmitter section that generates a transmission wave, a transmission/reception switching circuit that switches and transmits the transmission wave and the reception wave, and an antenna section that emits the transmission wave into the atmosphere and receives the radio waves in the atmosphere. , a receiver that converts the high-frequency signal received by the antenna into a video signal, and a video signal from the receiver that constantly maintains the distance difference between the distance to the tracking target and the distance displayed by the tracking radar device to a minimum, thereby determining the distance. a distance tracking unit that performs tracking; 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; An antenna drive unit that drives the antenna unit using an angular error signal from the tracking unit, and a speed of the target being tracked based on the amount of change in the distance signal from the distance tracking unit and the amount of change in the angle signal from the antenna drive unit. a measurement calculation unit that calculates
A shooting calculation section predicts the future position of the target and calculates the firing angle from the target speed signal from the measurement calculation section, and a shooting calculation section detects the Topple frequency from the received signal of the reception section and uses a frequency discrimination circuit to detect the target. Consisting of a direction discrimination section that performs direction discrimination, and a gate circuit that outputs only a video signal of a target that is found to be in an approaching position as a result of the direction discrimination performed by the direction discrimination section,
When the bullet passes near the target after firing, the gate circuit blocks the video of the bullet at a distance, thereby preventing a malfunction in which the shooting tracking radar device mistakenly tracks the video of the bullet. A shooting tracking radar device featuring:
