What are the units of Power and Intensity in radar measurements?

Power and intensity in radar measurements are expressed in specific units that relate to their physical meanings.

Power is defined as the rate at which energy is transferred or converted, and in the context of radar, it is commonly measured in watts (W), which is equivalent to joules per second (J/s). This unit reflects how much energy is emitted by the radar system over time.

Intensity, on the other hand, refers to the power per unit area, which gives an indication of how concentrated that power is over a particular surface. In radar measurements, intensity is typically expressed in terms of watts per square meter (W/m^2). This shows the amount of power distributed across a specific area, which is crucial for understanding the strength of the radar signal as it propagates through the atmosphere and interacts with precipitation or atmospheric phenomena.

These definitions align perfectly with the answer choice, making it the correct choice. The other options involve units that do not relate to the measurements of power and intensity in the context of radar.
