IWRL6432BOOST: Ideal steering vector table creation method

Nelson Lin2
Prodigy 120 points
Part Number: IWRL6432BOOST

Tool/software:

Hi,

In \radar_toolbox_2_30_00_12\source\ti\examples\Industrial_and_Personal_Electronics\Video_Doorbell\source\aoasvcproc\v0\aoasvcproc\v0\aoasv_table.c

Question 1: 2D Steering vector table(SteeringVectors[]) creation method:

  • In related code as below includes a Matlab script for generating steering vectors 'raw' data and saving to steering_vec.dat file
  • But the data of 2D Steering vector table(SteeringVectors[]) are not equal to 2D Steering vector 'raw' data in the steering_vec.dat → any conversion needed? may TI provide conversion script?

Question 2: 1D Steering vector table(SteeringVectors[]) creation method:

  • In related code includes a Matlab script to convert azimSteeringVectors25.mat to 1D Steering vector table
  • Not include azimSteeringVectors25.mat → may TI provide how to create this mat file?

Question 3: If we would like to design custom center frequency(not approx. 61 GHz mentioned in the reference below), any modification needed for ideal steering vector table creation method or somewhere?

Reference:

Best,

Nelson

    The steering vectors in the demo code are from empirically measured values at TI. The software for generation in MATLAB yields the theoretical results, not the measured results.

    We do not support 61 GHz with this method at this time.

    Yes, the measured Steering vector table(SteeringVectors[]) is what we need. May you provide the measurement method for 1D/2D Steering vector table(SteeringVectors[]) creation?

    Does this measurement method also help for custom center frequency?

    Hi,

    You will have to record the radar cube at various locations of the radar and corner reflector. We do not provide a way for customers to replicate this unfortunately. You may use our coefficients at 60 GHz, or you may collect your own, but we cannot support your data collection outside of the aoasvcdpu documentation.

    Best,

    Nate
