Which type of scanning is specifically used in fire-control tracking radars?

Monopulse scanning is specifically used in fire-control tracking radars due to its ability to provide accurate and rapid tracking of targets. This method employs a single pulse to simultaneously receive signals from multiple antennas, allowing for the precise determination of a target’s angle and position without the need for the radar system to move or scan across its field of view.

The key advantage of monopulse scanning lies in its speed and accuracy; it significantly reduces the time needed to track a target compared to other methods like sequential or single-pulse scanning. Monopulse systems can quickly adjust to changes in target position, making them particularly effective in environments where targets are maneuvering rapidly, such as in military engagements.

In contrast, other types of scanning such as electronic, single pulse, or manual scanning have various limitations regarding speed, accuracy, or responsiveness to target movement. For example, electronic scanning uses phased array antennas to add agility but does not match the pinpoint accuracy of monopulse systems in tracking.
