SFCW Signal Generation of Dual Frequency Channel Using LabVIEW Simulation

This paper describes the modelling process the dual channels SFCW signal generation using LabVIEW software. The developed signal generator can be used for any frequency range as well as single or dual channels. The designed user interface was kept as simple as possible. The dual channel SFCW signal generator was tested using two frequency range: 1MHz to 401MHz and 401MHz to 801MHz for channel one and two respectively. Both channel of stepped-frequency continuous wave (SFCW) radar signals has 400MHz bandwidth and divided into 8 steps with 50MHz of frequency step size. The aim of this paper has been achieved. A simulation of dual frequency channels SFCW signal generator is implemented in LabVIEW software. The SFCW waveform from both channels have been deconstructed and the frequencies component present in the generated SFCW waveform has been plotted which reflect the calculated frequencies components of 1MHz, 51MHz, 101MHz, 151MHz, 201MHz, 251MHz, 301MHz, 351MHz for channel one and 401MHz, 451MHz, 501MHz, 551MHz, 601MHz, 651MHz, 701MHz, 751MHz for channel two. The SFCW radar system are designed to generate the signals concurrently.
