M94 Muzzle Velocity System is used to measure the muzzle velocity of field artillery weapons.
The MVS is a lightweight, state-of-the-art radar designed for employment with field artillery units. It uses the Doppler principle in conjunction with digital signal processing to measure weapon muzzle velocities and automatically correct them for nonstandard conditions. The MVS will enable artillery batteries to eliminate gross range bias errors, a large contributing factor to artillery inaccuracies. This system will measure all types of field artillery rounds, to include base-bleed and rocket assisted projectiles. It will be reliable, supportable, and easily maintained. The MVS will incorporate built-in-test capability for immediate fault isolation of system failures. The system will consist of an antenna, an antenna bracket assembly, remote display unit, antenna cable/cable reel, and a transport case. The system will interface with the already fielded Battery Computer System (BCS) Gun Display Unit/M90 Chronograph power interface cable once the cable is modified.
The M94 MVS will replace the M90 Radar Chronograph at the battery level. The Marine Corps intends to field two M94s for every M90.
