Radar Equations

Radar equations for searching and tracking. Synthetic aperture radar (SAR) form of the radar equation, signal-to-noise ratio versus range plot, probability of detection versus range plot

Compute the maximum detectable range, SNR versus range, peak-power versus required SNR, minimum power-aperture product versus SNR.
