Radar Range Equation
</dt>
The relation between the maximum range Rmax at which a point target is detectable
and the properties of the radar and the target
R_{max} = [(PA^{2}λ^{2}σ)/(4π)^{3}S_{min})]^{1/4}
where P is the transmitted power of the radar; λ is its wavelength; σ is the scattering cross section of the target; A is the antenna gain; and S_{min} is the threshold signal. [[/a>|/a> ]]
