One preferred embodiment of the present invention provides a system and method
for suppressing motion artifacts introduced by movement of a radar detection system.
Briefly described, in architecture, one embodiment of the system, among others,
can be implemented as follows. The system includes a Doppler radar module configured
to transmit a microwave signal directed towards an object and receive the reflected
microwave signals from the object and a living subject positioned behind the object.
Also, the system includes a reference module configured to transmit a reference
signal towards the object and receive the reflected reference signal from the object.
By comparing the two reflected signals from the Doppler radar module and the reference
device, a signal processor suppresses motion artifacts generated by movement of
the Doppler radar module to identify the presence of the living subject behind
the object. Other systems and methods are also provided.
