BR-2401
The BR-2401 Doppler radar antenna has been especially designed for muzzle velocity measurements on small calibers.
Description
The BR-2401 Doppler radar antenna utilizes the Doppler principle to measure the velocity of moving objects. It is particularly well suited for muzzle velocity measurements as well as short range velocity measurements and rate of fire. This radar unit is ideal for measuring on small caliber 5.56mm 50cal projectiles.
The radar antenna consists of a transmitting and a receiving antenna (bi-static configuration) based on microstrip antenna technology. The receiver has a very low noise figure in order to provide maximum sensitivity and detection range.
Integrated acquisition and analog processing allows the unit to directly connect to the host computer through a single Ethernet cable.
The unit is powered using 12Vdc, which is provided by a sealed external power supply. Also, the trigger device (acoustic or optical) can directly be connected to the radar head for maximum convenience.
Rugged Construction
The BR-2401 housing is made of machined aluminum and provides outstanding rigidity in a small dimension and low weight package. The entire unit is sealed to prevent dust and water from getting inside the housing and damaging the electronics. This radar is specifically designed for small arm calibers, not to be used with artillery with excessive vibration and shocks. The radar head can easily be mounted on a standard photo tripod using a ¼”-20 screw. It is also possible to mount the antenna on a high caliber gun/tank barrel with the appropriate mounting bracket.
