Abstract
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.
