Explanation: The Synchronizer, often called the master timer or modulator, is the central component that generates all the timing pulses for the RADAR system. It ensures precise coordination between the transmitter, receiver, and indicator. The synchronizer triggers the transmitter (e.g., a magnetron) to emit a pulse, gates the receiver to "listen" for return echoes during the appropriate time window, and synchronizes the display to show the range information accurately. This precise timing is crucial for calculating target distance and avoiding interference from the transmitted pulse itself. The power supply provides electrical energy, but not timing signals. The indicator displays the processed data, while the receiver detects and amplifies incoming echoes; both operate under the timing control of the synchronizer.
