The present disclosure relates to a radar device and technique for
detecting the presence of objects located in the near-field of a
frequency modulated, continuous wave (FMCW) radar device. The technique
includes transmitting and receiving a frequency modulated signal,
generating an intermediate frequency signal based on the transmitted and
received signals, and analyzing the frequency content of the intermediate
frequency signal. The frequency content of the intermediate signal is
analyzed without filtering out a carrier signal.
