Doppler radar formula

The radar sensor measures distances, movements, and velocity. The sensor calculates the distance to an object by measuring the reflection of a high-frequency signal from that object . The transmitted signal is reflected by buildings, liquids, and so on.

The radar range equation represents the physical dependences of the transmit power , which is the wave propagation up to the receiving of the echo signals.
