Minimum detectable signal. ie, Pr = PtGσAe/ (4π)2R4. The maximum range of radar, Rmax is the distance beyond which the target cannot be detected. It occur when the received signal power, Pr = minimum detectable signal, Smin. Therefore, Smin = PtGσAe/ (4π)2Rmax4. Rmax = [PtGσAe/ (4π)2 Smin]1/4. This is the fundamental form of radar range equation.

Minimum Detectable Signal. If the echo signal has minimum power, detecting that signal by the Radar is known as minimum detectable signal. This means, Radar cannot detect the echo signal if that signal is having less power than that of minimum power. In general, Radar receives the echo signal in addition with noise.

The lower the frequency, the longer the range. However, the lower the frequency, the lower the data rate it can support.
