Abstract
A chronograph uses a Doppler radar technique to determine the muzzle velocity of a bullet discharged from small arms such as pistols and rifles. A radar unit is placed in near proximity to the firearm to track the bullet while it is still relatively close to the muzzle. The radar unit is equipped with an antenna which is insulated from the sonic disturbance created by the firearm blast by sonic damping means formed exteriorly on the antenna. Measured spacing and orientation of the antenna with respect to the firearm diminishes the sensitivity of the antenna to the electromagnetic disturbance associated with the firearm blast. Doppler signal processing means are also disclosed.
