Muzzle Velocity Radar (MVR)

The RSL AFA MVR (Advanced Field Artillery Muzzle Velocity Radar) system measures and manages a wide variety of ammunition for Field Artillery, Naval, Mortars and Anti-aircraft applications.The system provides accurate muzzle velocity data which significantly increases the first round hit probability.

RSL's MVR is used worldwide by many major armed forces.

Selected as the Standard Muzzle Velocity System for the US Army and Marine Corps
Designated as M94 by the US Army for all types of field artillery guns and as M93 for the M109A6 PALADIN self-propelled Howitzer

System Components

Integrated Transceiver(ITRAN)

The ITRAN contains the RF unit and Muzzle Velocity Processor (MVP). The RF unit is based on a X-band compact transceiver that generates a Doppler signal related to the velocity of projectiles fired from the gun on which the transceiver is mounted. The MVP is a DSP based processor that performs all the Muzzle Velocity
