Abstract

This paper presented an implementation method of single antenna short range wideband FMCW radar with microstrip structure, and the radar worked at 3 GHz. Microstrip Wilkinson power dividers were adopted to replace the traditional circulator duplex structure, and a wideband microstrip slot antenna was designed. Blackman window was applied into the frequency beat signal so as to decrease the effect of direct reflection, crosstalk. Experimental results show that the proposed method is feasible.

Key words

frequency modulation continuous wave (FMCW) radar / Blackman window / wideband antenna / microstrip power divider
