IWRL6432BOOST: calculation of range axis

Tool/software:

Dear colleagues,

I want to double check from your side.

I consider that IWRL6432 works in a complex 1x sampling mode.

Is it correct to calculate maximum range like this:

IFmax = 0.9 * ADCsampling
range_max = IFmax * c / (2*S)

2)

Am I right that ADCsampling = 2.5 Ms/s in case of

local sample_rate_divider = 20 ?

in script

"/radar_toolbox_2_20_00_05/tools/scripts/mmWaveStudio_luaExamples/IWRL6432_capture.lua"

Best regards,

I think I have figured out. As IWRL6432 has real mixer, the IFmax should be calculated like:

IFmax = 0.9 * (ADCsampling) / 2

but sample_rate_divider should be equal to 40 for ADCsampling = 2.5 Ms/s.

Hi Grigor,

Sorry about the slow response here. IWRL6432 has real-only sampling. Your understanding is correct in your latest reply.

Best Regards,
