Radar timing is typically expressed in microseconds because this unit provides a suitable level of precision needed for the measurements involved in radar operations. Radar systems rely on the accurate timing of signals to measure distances and detect objects. Given the speed of light, which is approximately 299,792 kilometers per second, microsecond resolution allows radar systems to determine distances accurately. For instance, a radar signal takes about 6 microseconds to travel 1,800 kilometers, making microseconds the most practical choice for radar timing.

While seconds, milliseconds, and nanoseconds are all valid units of time measurement, they do not provide the same level of granularity that is essential in radar applications. Seconds are too coarse for the high-frequency signals used in radar systems, while nanoseconds, though more precise, are usually excessive for the typical timing needs in radar processing. Thus, microseconds strike the right balance for effective radar timing and data interpretation.
