If obstructions affect coverage of the AN/TPQ-50, what is the minimum azimuth coverage an operator can select?

The minimum azimuth coverage that an operator can select when obstructions affect the coverage of the AN/TPQ-50 is 15°. This setting allows for adequate coverage while taking into account the impact of physical obstructions in the environment. The choice of 15° strikes a balance between maximizing detection capabilities and minimizing blind spots created by obstacles such as buildings, trees, or terrain features.

Selecting a wider coverage, like 20° or 30°, may reduce the radar's ability to accurately track incoming threats, particularly if obstructions interfere with the radar's line of sight. A narrower coverage, such as 10°, could be inadequate to effectively monitor the desired area, especially in the presence of obstructions. Thus, 15° is the minimum that enables the operator to maintain functional radar performance while addressing challenges posed by the surroundings.
