What is the primary role of a radar receiver?

• A. To transmit radar waves
• B. To capture reflected signals and convert them into usable data
• C. To enhance signal modulation techniques
• D. To increase the radar's operating range

Answer: (B)

The primary role of a radar receiver is to capture reflected signals and convert them into usable data. This process is essential for radar systems, as it allows them to detect and analyze objects within their range. When radar waves are transmitted and bounce off an object, they return to the radar system as reflected signals. The receiver processes these signals, extracting information such as distance, speed, and angle of the objects, which are crucial for interpreting and displaying radar data. The other roles mentioned can be important in different contexts but do not represent the primary function of the receiver itself. The transmission of radar waves is the responsibility of the radar transmitter, and while enhancing signal modulation techniques or increasing the radar's operating range may improve system performance, these functions are not the core responsibility of the receiver. Thus, capturing and converting reflected signals is fundamentally what defines the radar receiver's purpose in a radar system.
