How many points must radar zones have at a minimum?

Radar zones must have a minimum of three points to ensure effective coverage and accurate detection of enemy artillery fire. This requirement stems from the need for triangulation, which allows the radar to determine the location of a threat by measuring the time it takes for signals to return from multiple points.

When there are at least three points, the radar can create a more defined area that enhances its ability to track and analyze incoming projectiles or artillery fire. The additional points help reduce ambiguity in calculations and improve the accuracy of the data provided to operators, leading to more effective counter-battery operations.

In contrast, having fewer than three points could result in uncertain or less reliable information, as the necessary triangulation process would be compromised. Thus, three points represent the minimum requirement to maintain a high level of operational effectiveness in radar zone establishment.
