RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

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).
Keep all units consistent. Losses due to atmospheric absorption and antenna polarization are not included.
