Which of the following refers to the ability of a radar system to handle echoes from multiple targets?

The correct answer is resolution capability, which refers to a radar system’s ability to distinguish between multiple targets that may be very close together in range or bearing. This capability is essential for effective target discrimination; for example, in scenarios involving closely spaced aircraft or multiple objects in the water, a radar system with high resolution capability will be able to identify and track each target separately rather than merging them into one echo.

Resolution capability is crucial in applications such as air traffic control or collision avoidance, where accurate identification of numerous aircraft or obstacles is important for safety and operational efficiency.

Signal processing pertains to the techniques used to analyze and interpret the radar echoes, but it does not directly describe the ability to differentiate between multiple targets. Clutter rejection involves filtering out unwanted signals from stationary or irrelevant objects, which can improve the clarity of target detection but does not specifically denote the ability to handle multiple targets. Beam width refers to the angular width of the radar antenna’s radiation pattern; while it can influence the resolution, it is not the defining characteristic of target discrimination.
