Abstract

With the growth of broadband wireless technology like code division multiple access (CDMA) and ultra-wideband (UWB), lots of development and efforts towards wireless communication system and imaging radar system are well justified. Efforts are also being imparted towards a convergence technology involving both communication and radar technology which will result in intelligent transport system (ITS) and other applications. The authors have tried to converge the communication technologies towards radar and to achieve the interference free and clutter free quality remote images of targets using DS-UWB wireless technology. In this paper, we propose a direct sequence spread spectrum (DSSS) radar for remote sensing in ITS system. We have successfully detected single target using 1D radar imaging, and also separated multiple targets and implemented DSSS radar using software defined radio (SDR) to get continuous connectivity of the system. Authors have sought down the limitations of DSSS radar which according to them can be solved by using adaptive equalizer and rake processing.
