1. Two TestCases(TestCase004/TestCase006) for capture ADC Data and show desult for the same scene.
1.1 It seems two TestCase capture ADC data correctly,
The 1DFFT/2DFFT result on TestCase006 is strange, it is very different with TestCase004, and there is direct component.
Thourgh TestCase004 and TestCase006 have different Profile and Chip params, but I expect the 1DFFT/2DFFT result should be similar.
Does the data layout in ADC data file captured is differnet for the two Cases.
1.2 scene, the chair is is about 2.00 meter in front of IWR6843ISK EVM
1.3 Two TestCases
TestCase004
use mmWave Studio to capture ADC binary,
below is 1DFFT/2DFFT result with matlab
TestCase006
use mmw demo and open LVDS with CLI "lvdsStreamCfg -1 0 1 0"
below is 1DFFT/2DFFT result with matlab
1.3 Environment:
IWR6843ISK EVM
DCA1000EVM
