What is the primary function of the trigger/master clock in radar systems?

The primary function of the trigger, or master clock, in radar systems is to indicate when the radar should transmit or receive signals. This timing mechanism is essential for the radar’s operation as it ensures that the emitted radio waves are sent out and then properly received back after reflecting off an object, such as precipitation or another surface. This precise timing allows for accurate calculation of distance and speed based on the time it takes for the signals to return.

The trigger also helps coordinate the radar's functions effectively, ensuring that all system components work together seamlessly during the transmission and reception processes. Without this synchronization, the radar would struggle to produce accurate and reliable data, making it difficult to interpret the results.

In contrast, while synchronizing radar components is important, it is more of a secondary function as the primary task focuses on controlling when the radar operates. Other functions like frequency adjustment and power regulation are managed by different parts of the radar system and are not the core role of the master clock.
