What key factor influences the range of a Pulse Radar device?

The range of a Pulse Radar device is significantly influenced by the power output of the radar signal. A higher power output allows the radar to transmit stronger signals, which can travel further before being absorbed or scattered by the environment. This increase in signal strength improves the ability of the radar to detect targets at greater distances, as the echoes received back from those targets remain discernible above the noise. Therefore, the power output is directly related to both the signal's ability to travel long distances and its effectiveness in detecting distant objects.

Although other factors such as frequency and calibration can also play roles in the overall performance of a radar system, they do not primarily influence the maximum range in the same way that power output does. For instance, while frequency can affect radar resolution and susceptibility to scattering in different environments, it is the power output that predominantly determines how far the radar signal can travel and still effectively return usable data.
