Kraken app heatmap

Hi,

The documentation about how the heatmap and location finding in the app works mentions using all 360 degrees of output to do a bit of averaging and to make use of minor peaks as well as just the main one. Is this done by summing the doa output from every datapoint pointing to each heatmap pixel? and the largest sum would be the signal source’s location, or is there some averaging or normalising going on?

Thank you,

Yes for each frame of data, each heatmap cell is activated by one count multiplied by the DOA output value. Over time the grid effectively averages the DOA data spatially with the largest value cell being where the TX is.
