Which part of a RADAR system is used for determining the angle of target direction?

The component of a radar system responsible for determining the angle of target direction is the antenna synchro transmitter. This device plays a crucial role in transmitting the angular position of the radar antenna. As the radar antenna rotates to scan a designated area, the synchro transmitter generates signals that reflect the precise position of the antenna at any given time.

This positional information is vital for accurately directing and interpreting radar signals. By providing real-time angular information, it aids the signal processing unit in correlating detected signals with specific angular positions, allowing for accurate targeting and tracking of objects.

While the antenna rotation mechanism is responsible for the physical movement of the antenna, it does not provide information about the angular position. The signal processing unit analyzes the received signals but relies on data from the synchro transmitter to apply the appropriate angle to target information. The receiver unit's main function is to capture the backscattered signals from the target but does not determine the angle of direction. Hence, the synchro transmitter is essential for establishing the angle of target direction in a radar system.
