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.

A Doppler radar sensor includes a radar and a bondwire interconnection. The bondwire interconnection is connected to a signal generator and an antenna of the radar and configured to transmit a radio frequency signal generated by the signal generator to the antenna and transmit a reflected signal received by the antenna to a demodulator of the radar. A metal strip, a first shunt bondwire and a second shunt bondwire of the bondwire interconnection can be used as a matching circuit of the antenna to decrease the transmission loss and increase the detection distance of the radar.
