These are the tried & true radar equations used for decades and can be found
in many textbooks and desk references. Transmitter power, target distance and radar
cross-section (RCS) are used along with free-space loss (Friis equation), and antenna gains
to calculate the power that arrives at the input of the receiver. These equations
cover both monostatic radar where the transmitter and receiver are in the same location
and bistatic radar where the transmitter and receiver are in different locations
(see drawings).
Here is information on propagation time,
path loss, and Doppler.
Keep all units consistent. Losses due to atmospheric absorption and antenna polarization
are not included.
Monostatic Radar Equation (Tx and Rx in same location)

Bistatic Radar Equation (Tx and Rx in different locations)
 (wavelength)
 (frequency)
(convert to dBW)
