Abstract
This paper describes the modelling process the dual channels stepped-frequency continuous wave (SFCW) signal generation using LabVIEW software. The developed signal generator is a flexible system where it can be used for any SFCW radar application with different frequency range as well as single or dual channels. The system is presented using two frequency range: 1MHz to 401MHz and 401MHz to 801MHz for channel one and two respectively. Both channels have 400MHz bandwidth and divided into 8 steps with 50MHz of frequency step size and generated concurrently. As the result, two waveforms are produced after generating the signals based on the mentioned parameters. The proposed dual-channel SFCW signal generator was then analysed and validated by deconstructing the generated signals from both channels to obtain frequency components that exist in each channel. The deconstructed 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.
