Radar Heads with Motion
To overcome the limited measurement range of fixed head radar solution, models with higher antenna gain and transmitter power are offered along with pre-programmed motion capabilities. To be able to achieve long range detection, it is necessary to move the radar head during a measurement to point the radar towards the flying projectile throughout the trajectory. If the antenna does not move, the projectile may fall outside of the antenna beam and the radar signal is lost.
A typical system with motion capabilities consist of the following items:
- Radar antenna.
- Motion head with pan & tilt capability.
- Motion controller.
- Junction box.
- Operator PC computer.
- TestCenter software.
The TestCenter software calculates a ballistic trajectory that is used to setup a motion profile for the radar. By refining the prediction, it is generally possible to follow the actual projectile until it reaches the impact area.
The radar antenna is mounted on the pan & tilt head. The whole radar assembly is installed on a tripod. The motion controller provides the necessary logic to control the motion and it is under the control of the remote PC computer. The radar is connected to the junction box using a long signal cable (ex: 100 meters). The junction box located at the console is connected to the PC computer and it is used to digitize the Doppler signal generated by the radar. The TestCenter software then processes that signal and extract the velocity information along with other results. A trigger device is required to synchronize the acquisition with the muzzle exit event.
The typical applications for a radar system with motion capabilities are:
- Long range measurement on artillery.
- Measurement on mortars.
- Firing table determination.
- Etc.
