Actually, for one object at position [Range,Doppler], the power spectrum contains 12 spots, one for each Tx. In line 175, find_TX0_position aims to identify among the 12 spots, which one is the Tx0. Then, knowing the doppler position of Tx0, line from 179 to 181 aim to extract all the other Tx position. That is to say Tx positions will be something like this ([Tx0 Tx0+641 Tx0+642...]) % 256
