**Part Number:**MMWAVE-SDK

hello ,i have a question about Doppler DDMA dpu process method in the picture as follow,the picture is from "mmWave SDK Module Documentation-DPU-Doppler DDMA":

In my opinion ，use sum Rx and sum Tx is for Incoherent superposition，so i think the process sequence is “ABS DOP FFT result” ，”Sum RX“，”Sum Tx“，”log to change the result to dB“，if first use log to calculate the abs result，and then do the sum Rx and sum Tx，this means multiple the abs result not sum，because log（A） + log（B） = log（AB）。

Can anyone answer my question？thanks a lot.
