What must the Firefinder radar have an electronic line of sight to?

The Firefinder radar operates by detecting and tracking incoming projectiles and determining their launch point through the analysis of radar signals. For the radar to function effectively, it requires an electronic line of sight to the projectile being fired. This line of sight enables the radar to accurately capture and analyze the radar echoes from the projectile.

Without this direct view, the radar system would be unable to collect vital data necessary for determining the trajectory and origin of the projectile, ultimately hindering its ability to provide timely and accurate target location information for artillery response.

In contrast, while the command center or satellite communications may play important roles in overall operational effectiveness and connectivity, they do not directly impact the radar's fundamental capability to detect and track projectiles. The target location is also not a factor in establishing the necessary radar functionality; the radar's primary focus remains on the projectile itself.
