Abstract
In this paper, we design a prototype FMCW (Frequency Modulated-Continuous Wave) radar for short distance using universal software defined radio peripheral (USRP). USRP is an ideal platform for all type of telecommunication research, until the bandwidth requirement is fulfilled by universal serial bus (USB). The limited bandwidth of USB bus restricted to realize short distance radar on this platform using GNU-RADIO signal processing block. To avoid the bandwidth limitation, we build transmit section independently inside the FPGA, which free the transmit section bandwidth to be fully utilized by receiving section. The prototype performance test is carried out at the center frequency of 2.4 GHz with a bandwidth of 15 MHz. To avoid the clutter of the environment, directional antenna is used for better target detection at certain distances. The return target echo is further processed using MATLAB.
