Frequency modulated continuous wave (FMCW)radars offer many advantages such as low peak power, lowprobability of interception and low interference to othersystems. However, their major drawback is the isolationrequired between transmitter and receiver that typically leads tothe use of two separate antennas. Some schemes have beenproposed to enable FMCW radars to operate with a singleantenna, such as frequency modulated interrupted continuouswave (FMICW). A Stagger procedure was proposed toovercome the problems associated to the use of the FMICWtechnique in medium range high resolution radars (HRR). Amillimeter-wave radar sensor, in Ka-band, has been developedin the Universidad Politécnica de Madrid to validate the Staggertechnique. The sensor transmits a linear FMICW, with amaximum bandwidth of 2 GHz and a transmitted power of 29dBm. The system is low-cost, modular, compact and lightweight,so it is attractive for portable applications.
