Abstract
In this paper a method to realize a heterodyne frequency-modulated
continuous-wave (FMCW) radar is presented. The system operates at a
frequency of 77 GHz and is based on an in-phase quadrature-phase (IQ)
modulator in the transmit (TX)-path of the system. This IQ modulator is
used as a single-sideband mixer, which allows the realization of an
offset frequency between the radar's TX and receive signal. In this way
it is possible to shift the frequency band containing the target
information away from dc, which simplifies FMCW range measurement of
targets close to the radar.
