What type of signals does moving RADAR transmit?

Moving radar systems typically utilize a single transmitted signal that is sent out to detect objects and measure their distance or speed, while simultaneously receiving multiple signals that are reflected back from objects in the radar's path. This ability to analyze multiple received signals can help differentiate between various targets, providing valuable information such as their speed and distance.

In this context, the system is able to compare the transmitted signal with the returned echoes to extract important data. The radar's design allows it to be efficient in tracking multiple targets by analyzing the returned signals, which facilitates improved detection and measurement capabilities.

The other options consider different scenarios with either multiple transmissions or receptions that do not align with the standard operation of moving radar systems, which is generally designed for efficiency and accuracy with one transmitted signal operating effectively with multiple received reflections.
