What essential data does tracking radar provide for fire-control?

Tracking radar is primarily designed to provide continuous positional target data, which is critical for fire-control systems. This type of radar continuously monitors and calculates the positions of airborne or maritime targets, ensuring that accurate data is available for the engagement of those targets. Continuous tracking allows for real-time updates on the target's speed, direction, and distance, which are all essential for calculating firing solutions.

In contrast, while target elevation is important, it is just one aspect of targeting data rather than a continuous stream. General weather conditions and aircraft identifications serve different purposes and do not provide the continuous positional data required for effective fire-control. Therefore, the provision of ongoing and accurate positional information is what makes tracking radar invaluable in fire-control scenarios.
