What calibration checks are necessary before operating the Firefinder Radar?

The necessary calibration checks before operating the Firefinder Radar include verifying the radar's alignment and checking coordinates. Proper alignment ensures that the radar system accurately detects and processes incoming artillery fire, while checking coordinates is crucial for establishing a precise location from which to calculate the trajectory of the incoming rounds. This ensures that the data provided by the radar is accurate and reliable, which is vital for effective targeting and response strategies. Maintaining accuracy in these initial calibration checks minimizes the risk of errors in targeting, reducing the likelihood of miscalculations that could lead to ineffective counter-battery operations or collateral damage.

Other options may address important operational or maintenance aspects but do not directly pertain to the specific calibration checks required for the Firefinder Radar prior to its use.
