Abstract
In this paper we present a newly developed software
defined radar platform for mm-wave sensing applications. The
main features of this platform are up to eight analog-to-digital
and digital-to-analog converters with a sample rate of 500 MSPS
and 14-bit resolution for conversion and modulation. A 77-GHz
SiGe chip with an in-phase/quadrature (I/Q) modulator in the
transmit path and an I/Q receive mixer is used for radar mea-
surements. As a first outlook on the potential benefits, frequency-
modulated continuous-wave and range/Doppler radar measure-
ments are presented. In these measurements the frequency ramps
are solely generated in baseband and upconverted using the I/Q
modulator as single-sideband mixer. Ramp durations down to
1μs were experimentally verified at a bandwidth of 200 MHz.
