Muzzle velocity measurements: Artillery

Accurately measure and analyze artillery muzzle velocity in real-time with maximum reliability.

Achieve maximum firing accuracy


The ability to accurately measure and analyze muzzle velocity in real-time is critical when firing artillery. In fact, muzzle velocity data is as important as meteorological data and projectile characteristics to ensure the best possible firing accuracy, accounting for up to 40 percent of the error budget in artillery shooting.

Several factors can affect a round’s muzzle velocity, including weapon conditions, tube tolerance, ammunition lot variance, propellant conditions, crew performance, recoil system conditions and deployment. It is critical to compensate for these factors to achieve the desired accuracy by adjusting gun settings based on the actual muzzle velocity.

Artillery firing accuracy is described in terms of precision and bias. The objective is for multiple artillery rounds to strike a target with a small mean point of impact (MPI) and high precision.

Muzzle velocity data is necessary to ensure the best possible firing accuracy.

This has very real performance results. It reduces collateral damage in complex battle scenarios when firing artillery and other indirect weapons and the desired effect is achieved faster and with fewer rounds. This is important in “shoot and scoot” missions to maximize survivability, and it helps to reduce the total costs of operation. Effectively controlling the muzzle velocity gives you a better opportunity to achieve satisfactory results in both of these parameters.

Through features such as self-calibration and active motion compensation technologies, our muzzle velocity radars set the global standard for measurements of modern artillery with minimum maintenance and logistic requirements.

Our muzzle velocity radar is a straightforward, single-unit add-on to your weapon system. The system consists of an antenna with an integrated processor and an optional display unit placed near the gunner or battery commander.

Muzzle velocity is calculated using Fast Fourier Transform (FFT) and digital signal processing,
ranging from 30 to 3,000 meters per second.

The antenna unit contains all necessary electronics and an acoustic trigger. Its trigger and Doppler signals are digitized by the processor unit and stored for digital analysis immediately after recording. Its advanced trigger detection ensures correct operation, even when different nearby weapons are fired at the same time.

The result is visible to the Fire Control computer or on the optional display unit less than two seconds after fire.
