How wide is the search window for the AN/TPQ-36 in Friendly Fire mode?

The search window for the AN/TPQ-36 in Friendly Fire mode is indeed 440 mils. This measurement is crucial for effective radar operations, as it allows for a wider angular coverage to detect incoming projectiles while distinguishing friendly fire sources.

In Friendly Fire mode, the radar system needs to monitor a broad area to ensure that it can accurately identify the trajectories of incoming projectiles and differentiate them from friendly fire. A search window of 440 mils provides sufficient scope for the radar to operate effectively in identifying threats without misidentifying friendly units. This capability is essential for situational awareness on the battlefield and helps to prevent fratricide, ensuring that friendly forces can engage targets without risk to their own troops.

Understanding the specific width of the search window is pivotal for radar operators in ensuring optimal performance and accuracy in detecting incoming threats.
