Which type of radar is referred to as pulse, coherent, monostatic?

The choice that is identified as pulse, coherent, monostatic radar is the WSR-88D. This system, which stands for Weather Surveillance Radar - 1988 Doppler, utilizes a pulse radar design, meaning it emits short bursts or pulses of energy and then listens for the echoes that return from precipitation and other targets.

Being a coherent radar implies it uses stable oscillations which allow for the measurement of both the strength and velocity of targets, enhancing its operational capabilities in detecting different weather phenomena like precipitation intensity and movement.

The term monostatic indicates that the radar transmitter and receiver are located at the same site, which is typical in many radar systems used for weather surveillance, enabling a direct and effective analysis of the target returns.

In contrast, the other options represent different configurations or technologies. Meteorological Doppler Radar is a broader category that can encompass various radar types, while vertical beam radar typically focuses on specific elevation angles and does not inherently refer to pulse technology. Gridded radar systems are advanced configurations that may process and visualize data differently compared to traditional pulse radar systems.
