AWR2243p beam steering

Hello,TI

I am using TI’s AWR2243p cascaded radar. I have learned the theory of MIMO and beamforming. Now I want to know how I should set the value of the phase shifter in mmwave studio for beamforming, or should I modify it The .lua file in the C://ti//mmwave_studio_03_00_00_14//mmWaveStudio//Scripts//Cascade folder for beamforming settings. What I mean is to set the phase shifter for 12Tx.

    Hi

    Yes, please review the cascade scripts provided in the mmwave studio release

    Please also see the phase shifts introduced in the script of Cascade_Configuration_TXBF_Simple

    Thank you

    Hello,Cesar

    I have studied the matlab code under the 4chip_cascade_TxBF_example folder, and I found it can be used to configure beamforming.
    1. What do the three .m files in the rectangular box in the first picture mean?
    2. For the second picture, why is the setting of anglesToSteer a range instead of a specific value, for example, if I want my beam to be facing 60°, how should I set it?

    Hi,

    The three files provide different chirp configurations for Long Range (LRR) Medium Range (SMRR) and Ultra Short Range (USRR)

    In the files provided the use case is Sweeping angles from -30deg to 30deg with a step of 2deg.

    if you want to steer only to 60 could you try params.anglesToSteer=[60:0:60]

    Thank you
