What is the effective range of radar?

Radars have average powers from a few milliwatts to as much as one or more megawatts , depending on the application. A typical pulse waveform transmitted by radar. Encyclopædia Britannica, Inc. A weak echo signal from a target might be as low as 1 picowatt (10−12 watt).

The Radar Range Equation relates the range of radar to the characteristics of the Tx (Transmitter), Rx (Receiver), Ae(Antenna), target, and the environment . It is useful to determine the maximum range at which a particular radar can detect a target and its makes to understand the factor affecting radar performance.

Maximum Range: Radar Max Range is determined, ideally speaking, on the properties of the antenna only . A signal at a certain frequency is transmitted, reflected, then hopefully, detected. Due to the three-dimensional propagation of radar waves, frequency hold the highest weight in determining range.

Therefore, the maximum range of Radar for given specifications is 158KM .
