Part Number:IWR1443BOOST
According to the example given in Fluid-level sensing using 77-GHz millimeter wave white paper (http://www.ti.com/lit/wp/spyy004/spyy004.pdf),
These posts suggest to increase the Range FFT size which increase the no. of frequency bins of the FFT spectrum.
My question is, If we reduce the ADC sampling rate by factor of 2 say 5 MSPS (it decrease the frequency bin size) and does it increase the range resolution/range accuracy by a factor of 2?
Say, if we use Range FFT size 4096 and 1 MSPS ADC sampling rate, can we achieve range resolution closer to ~1 mm without using any special algorithm?
Is there any fundamental issue/ hardware limitation of doing so?
Thanks,
