Part Number: TIDEP-01012 Hello,
You mention in the document that "The elevation angle resolution is equivalent to the resolution achieved with 7 antennas." could you pelase explain regarding the following picture you get 7 VRA on the elevation ?…
Part Number: TIDEP-01012 Hi
My question is about the elevation resolution, please could you tell how you find 18° as elevation angle resoltion for the cascading radar x4?
Bascially we have 4 virtual antennas on elevation, am I right ?
Regards
Part Number: TIDEP-01012 Hello.
The reference design document shows that the beamforming capture, in an anechoic chamber after calibration, has lower sidelobes than that which can be seen in my capture. I performed calibration indoors and obtained a decent…
Part Number: TIDEP-01012 Hi,
I see that in the Cascade_Phase_Shifter_Calibration_AWRx.lua script, the sensors are configured in a loop from phase shifter value 0 to 63 which are in steps of 5.625 degrees. This translates to phases going from 0 to 354.275…

Hello.
The reference design document states that MIMO mode is capable of detecting targets at 150 meters. Using the specified MRR configuration, the following plot was obtained. What is the dip at the furthest range? Does this…

The following code is used to plot the range azimuth heatmap. Why is the magnitude raised to the power 0.2? Should this not be 20*log10(magnitude)? The code is in the file: "4chip_cascade_TxBF\PostProc\Plot_advFraConfig_TXBF_rangeAzimuth_stich…
Part Number: TIDEP-01012 I noticed that the calibration matrix is limited to a 30 degree beamwidth. Does this mean that in the MATLAB TXBF configuration script 'chirpProfile_TxBF_USRR.m', the default 'params.anglesToSteer=-30:2:30; ' is not valid? Or…
Part Number: TIDEP-01012 Hello TI Team,
I am trying to synchronize an external camera with the mmWave Cascade radar. Ideally, each frame of the camera should coincide with a frame from the radar. There are already posts on this topic see:

Part Number: TIDEP-01012 Hello Cesar ,One more query where I can find information about the data structure used for MATLAB scripts - 4chip_cascade_MIMO_example such as doppler_corr, dopplerInd_org,range,estSNR,rangeInd etc.
Also how can we log data for…
