What is the purpose of the scope on the AN/TPQ-50?

The scope on the AN/TPQ-50 serves as a backup alignment device that assists operators in ensuring that the radar system is accurately aligned with the intended field of view. This is crucial for maintaining the effectiveness of the radar's operation, especially in cases where primary alignment methods might fail or be compromised. The scope allows the operator to make manual adjustments and confirm alignment visually, ensuring that the radar can effectively detect and track artillery and mortar fire. This manual verification capability is especially important during field operations when rapid response and accuracy are essential for targeting and counter-battery fire missions.
