Gain for radar is primarily described in terms of what?

Gain for radar systems is primarily described in terms of intensity. This is because gain relates to how much amplification is provided to the radar signal, which translates to the intensity of the received signal compared to the transmitted signal. In radar systems, gain is crucial, as it determines the radar's ability to detect weak signals reflected from distant objects or targets.

While frequency, voltage, and wavelength are important parameters in radar operation, they do not directly pertain to the concept of gain. Frequency and wavelength are related to the signal's characteristics, and voltage can refer to the power supplied to the radar equipment, but gain itself specifically focuses on the enhancement of signal intensity used for detection and measurement tasks in radar applications.
