AWR1843BOOST: Phase difference for finding Z-axis and X-axis

Hiroyuki Kanematu
Expert 2975 points
Part Number: AWR1843BOOST


I have two questions below.

(1) When finding the Z axis
The following modules are used when obtaining the Z axis, but the values of the peakAzim and peakElev series are
Is it possible to check without visualizer?

Wz = atan2(peakAzimIm * peakElevRe - peakAzimRe * peakElevIm,
peakAzimRe * peakElevRe + peakAzimIm * peakElevIm)/PI_ + (2 * Wx);

(2) When obtaining the X-axis
The following modules are used when obtaining the X axis, but sMaxIdx and DPU_AOAPROCDSP_NUM_ANGLE_BINS
Is it possible to check the value?

Wx = 2 * (float) sMaxIdx / DPU_AOAPROCDSP_NUM_ANGLE_BINS

(* Lines 379 and 367 of aoaprocdsp.c, respectively.)

    Hi,

    Question (1) seems to be incomplete here. Regardless, you can try to observe the values you choose using the Code Composer Studio debugger. Load the default binaries, set breakpoint at required line & watch required expression. The steps can be found in section 3.2.2 of the mmwave SDK userguide.
