Hi
I try to use the Azimuth static heatmap to calculate the AOA for myself. I use AWR1843 and SDK 03_05_00_04, the AWR1843 demo document show following and I can get all of the complex data, but I do not know what is the data value means? Is it Q9 or Q8? is it log2 magnitudes value or not? if I assume it is log2 magnitudes value, I can not get the correct AOA of the target range bin , but if I assume it is pure magnitudes value , I can get the correct AOA of the target range bin. I can not find any TI document that can describe the formate of the Azimuth static heatmuth, can you help to clarify it?
TI documet only show Range Profile and Noise Profile all use Q9 and log2 magnitudes value, is this format correct?
Is Range/Doppler heatmap also use the same format?
Azimuth static heatmap
Type: (MMWDEMO_OUTPUT_MSG_AZIMUT_STATIC_HEAT_MAP)
Length: (Range FFT size) x (Number of virtual antennas) (size of cmplx16ImRe_t_)
Value: Array DPU_AoAProcHWA_HW_Resources::azimuthStaticHeatMap. The antenna data are complex symbols, with imaginary first and real second in the following order:
Imag(ant 0, range 0), Real(ant 0, range 0),...,Imag(ant N-1, range 0),Real(ant N-1, range 0)
...
Imag(ant 0, range R-1), Real(ant 0, range R-1),...,Imag(ant N-1, range R-1),Real(ant N-1, range R-1)
