置。A device that measures the velocity of a shell based on a Doppler signal corresponding to the velocity of the shell, which includes a microwave oscillator that generates a microwave signal to irradiate the shell, and a device that irradiates the microwave signal to the shell and that radiates the microwave signal from the shell. an antenna for receiving reflected waves from the shell, a transmitting/receiving switch connected to the microwave oscillator and the antenna, a mixer for detecting a Doppler signal from the reflected waves from the shell, a coupler for supplying a local signal to the mixer, It consists of a high-pass filter that removes impact noise that occurs when firing, an amplifier that amplifies the Doppler signal, a signal processing circuit that converts the Doppler signal into the velocity of the shell, and an indicator that displays the velocity of the shell. A shell speed measuring device characterized by accurately measuring the speed of a shell without being affected by generated impact noise.
