What is the purpose of a transceiver in radar systems?

The purpose of a transceiver in radar systems is to combine both transmitting and receiving functions into one unit. This integration allows for more compact radar system designs, as a transceiver is capable of sending out radar signals (transmission) and then receiving any reflected signals back (reception) within a single piece of equipment. By employing a transceiver, radar systems can efficiently operate by simplifying the overall architecture, reducing the number of separate components required, and improving the system's reliability.

The other options address aspects of radar system operation but do not reflect the main function of a transceiver. Amplifying signals is an important function within radar systems for clarity, but it is not the defining characteristic of a transceiver. Similarly, filtering out noise is a necessary process in radar but is typically handled by separate components rather than by the transceiver itself. Storing data for later analysis is also a crucial task but is managed by data processing systems, not directly by the transceiver. Thus, the correct choice accurately highlights the essential role of a transceiver in enabling efficient communication in radar applications.
