dbf doa

[iceice]

The beams number of dbfdoa in S32R274 demo is 64. How to modify the value and what are the limitations? I hope to obtain higher precision, is it possible to change 64 to 128?

Hello,

the dbfdoa is just an example for a particular use-case involving 128peaks

it's possible to calculate more but of course requires more processing time.

The example is provided as reference and can be extended as needed. please refer to RSDK user manual for details on functions.

Best regards,

Peter

This manual is terrible. Do you have more details?

[petervlna]

Hello,

No there is not other explanation.

Furthermore,

Changing the number of beams is complicated - you would need to know about radar algorithms and DSP to do this.

In general terms you need to generate new steering vector with more beams.

This would require some deep support.

Best regards,

Peter

I have a 128beams steering vector, which was proved correct in matlab, but I don't know how to modify spt

Hello,

Ok. But as I said. This will require support from RADAR team.

I am not able to give you more information on this.

In order to get in touch with RADAR team please submit the ticket at NXP web or contact NXP FAE/Sales if you have one.
