SFCW Radar

[yuxin cai]

Dear Developer, 

Thank you so much for the sharing session recording posted on gprMax Channel. 

Here is a question i would like to ask regarding the video talking about impulse and SFCW:

1. After post simulation processing and obtaining the frequency domain response in complex form for each step frequency, may i ask how should i proceed on plotting A scan for this position point? 

 (Since one position one trace, Maybe need to obatin the range profile? Or somehow combine these N steps response to a whole? i am quite confused)

Looking forward to your reply. 

Best Regards 

Yuxin

The process described synthesise a single A-trace using the Impulse response instead of a single model for every frequency step. At the end of this process the iFFT gives a time domain trace. If you want to build a scan you need to repeat the process for every new position which means a new impulse response etc. I am not sure if the question was about something else. The loop in the picture builds the frequency response for a single Ascan by gathering the frequency components and constructing the complex frequency response ready for the iFFT. NumberPulses are the frequency steps in the SFCW radar.

Hope this helps
