Continuous Wave) radar is widely adapted due to the use of solid
state microwave amplifier to generate signal source. The FMCW
radar can be implemented and analyzed at low cost and less
complexity by using Software Defined Radio (SDR). In this
paper, SDR based FMCW radar for target detection and air
traffic control radar application is implemented in real time. The
FMCW radar model is implemented using open source software
and hardware. GNU Radio is utilized for software part of the
radar and USRP (Universal Software Radio Peripheral) N210 for
hardware part. Log-periodic antenna operating at 1GHZ
frequency is used for transmission and reception of radar signals.
From the beat signal obtained at receiver end and range
resolution of signal, target is detected. Further low pass filtering
followed by Fast Fourier Transform (FFT) is performed to
reduce computational complexity.
