Which component of Pulse Radar is responsible for sending and receiving signals?

The transceiver is the component in pulse radar systems that plays a critical role in both transmitting and receiving signals. It combines both transmitter and receiver functionalities, allowing it to generate the radar pulse and then process the echoes that are reflected back from targets. This dual functionality is essential for the radar system to detect the presence, distance, and speed of objects in its environment.

The antenna, while vital for directing and capturing radar waves, does not generate or process signals on its own. Its role is primarily focused on the transmission and reception of electromagnetic waves. The signal processor is essential for analyzing the received signals, including filtering and interpreting the data, but it does not directly handle the sending and receiving functions. The battery provides power to the system but does not interact with the radar signals.

In this context, the transceiver's capability to handle both transmission and reception of radar signals makes it the correct choice in identifying the key component responsible for sending and receiving signals in a pulse radar system.
