What is the synchronizer and what does it deal with?

• A. The Heart of the RADAR System; timing of trigger pulses, indicator sweep circuits, and ranging circuits
• B. A simple timing device for the transmitter only
• C. A cooling mechanism for the transmitter
• D. A receiver power regulator

Answer: (A)

The synchronizer is the timing control that keeps the radar in rhythm by coordinating when the transmitter fires, when the receiver gate opens, and how the display sweep and range circuits run. It starts the transmitter pulse and simultaneously triggers the receiver’s gating and the indicator’s time base so that echoes are shown at the correct position on the range display. This alignment makes the range measurement accurate because the display’s time axis directly corresponds to the round-trip time of the radar signal. If this timing isn’t synchronized, echoes could be mis-timed on the display, making range readings unreliable. So, it’s the central timing element that ties together trigger pulses, the indicator sweep, and the ranging circuits. The other options miss this coordinated timing role: a transmitter-only timing device, a cooling mechanism, or a regulator for receiver power don’t manage the overall timing and display synchronization.
