Frequency-Modulated Continuous-Wave Radar (FMCW Radar)

WebInstead, the FMCW radar emits an RF signal that is usually swept linearly in frequency. The received signal is then mixed with the emitted signal and due to the delay caused by the time of flight for the reflected signal, there will be a frequency difference that can be detected as a signal in the low frequency range. Webmodulated signal source is operated by modest power in FMCW radar [2], [3]. In this paper, the FMCW radar is utilized through both hardware and software source. Here, GNU Radio and USRP N210 with Log-periodic antenna to transmit and receive radar signals acts as software and hardware part respectively. grandson background https://pabartend.com
