One way radar range equation

The maximum unambiguous range (Rmax) is the longest range to which a transmitted pulse can travel out to and back again between consecutive transmitted pulses . In other words, Rmax is the maximum distance radar energy can travel round trip between pulses and still produce reliable information.

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.
