Claims

[Scope of utility model registration request]

A microwave oscillator that generates a microwave signal to irradiate the shell, an antenna that irradiates the microwave signal to the shell and receives reflected waves from the shell, and a mixer that detects a Doppler signal from the reflected wave from the shell. , a transmitter/receiver switch that sends the output signal of the microwave oscillator to the antenna during transmission, and sends the reflected wave received by the antenna to the mixer during reception, and removes impact noise generated during shooting from the output signal of the mixer. a discriminator that detects the frequency of impact noise from the output signal of the switched capacitor filter, and a discriminator that detects the frequency of the impact noise from the output signal of the switched capacitor filter; A variable clock generator that sets the cut-off frequency, a receiver that amplifies the output signal of the switched capacitor filter to the level required for signal processing, and a receiver that calculates the velocity of the cannonball from the output signal of this receiver. A radar device comprising: a signal processor for displaying signals;
