General Description
The BR-1022 Doppler radar antenna utilizes the Doppler principle to measure the velocity of moving objects. It is particularly well suited for measuring the velocity at the gun muzzle but is also powerful enough to measure velocity at a short and medium range, for projectile calibers ranging from 5.56mmm to 155mm including standard projectiles, base-bleed, tracers, APFSDS, sub-calibers, rockets, etc.
The radar antenna consists of a transmitting and a receiving antenna (bi-static configuration). The transmitter output power can be selected between 0.2W and 2W to accommodate short and medium range measurements. The receiver has a very low noise figure in order to provide maximum sensitivity and detection range. It also provides adequate filtering to reduce the likelihood of interference from other nearby radars operating in the same frequency range.
When used in conjunction with Infinition’s junction box and TestCenter Doppler processing software, it provides a powerful tool for ballistic analysis.
Rugged Construction
The BR-1022 housing has been designed using magnesium casting to provide excellent rigidity while minimizing its weight. The entire unit is sealed to prevent dust and water from entering the housing and damaging the electronic components. The radar is painted white to minimize sensitivity to the heat generated by the sun. The BR-1022 unit can operate under a wide range of temperature and weather conditions.
Performance
The performance of the BR-1022 unit has been calculated based on actual measurements on different projectile calibers. The range performance in the table below takes into account the effect of the projectile aspect angle along the trajectory.
| Caliber | Range Performance (typical / maximum) |
|---|---|
| 5.56mm (-58dBsm RCS) | > 500m / 700m |
| 155mm (-25dBsm RCS) | > 3300m / 4600m |
