Abstract
A Doppler radar sensor with a power detector is disclosed. In the Doppler radar sensor, a power detector is provided to detect the power level of a received transmission signal, and a leakage and clutter canceler is provided to generate a cancellation signal according to the power level of the received transmission signal. The cancellation signal is used to cancel leakage and clutter in the received transmission signal such that object displacement in the received transmission signal can be identified.
