Hi,

I tried to extend steer angles from [-30:2:30] to [-30:1:30] (mmWaveStudio\MatlabExamples\4chip_cascade_TxBF_example\chirpProfile_TxBF_USRR.m), but the test as follow result was wrong, there were so many peeks in result.I used mmwcas-rf-evm(2243) , mmwcas-dsp-evm and mmwavestudio-2g. I modified paramsConfig.anglesToSteer  [-30:1:30] in cascade_TxBF_signalProcessing.m at the same time.

My questions as fallow:

1、How to extand scope of angle streer

2、In TIDEP-01012(http://www.ti.com/lit/ug/tiduen5a/tiduen5a.pdf?ts=1591606682999&ref_url=http://www.ti.com/tool/TIDEP-01012  )

     3.4.2   the steer angle  [-60, 60] step 0.5 , Did this test use the mmwavestudio and mmWaveStudio\MatlabExamples\4chip_cascade_TxBF_example\  to capture and handle data?

    Hi user6350392, 

    I am looking into this issue. It will take me a few days to  get back to you. It sounds like you are covering all of the necessary parts in the code to modify. But I will check out the code too. Please let me know if you have found anything else. 

    Thank you,

    -Randy

    Hi Randy,

    Thank you for your reply. Did this problem cause by  TDA2XX hardware limit? I saw in sdk  doc (ProcessorSDKRadar_DevelopmentGuide.pdf) the radar data was handled as an image frame.The doc ProcessorSDKRadar_DevelopmentGuide.pdf defined radar image as follow:

    “width” of the frame is defined by the number of ADC samples captured per Chirp times the number of receive antennas and the “Height” of the frame is defined by the number of chirps times the number of transmit antennas in a given frame.

    In the case dbf [30:1:30]   height 3904 (61 * 64)  > 2048    (VPS_VIP_MAXSIZE_MAX_HEIGHT defined in vps_captureVipDataTypes.h in sdk)
