Part Number: MMWAVE-SDK
Other Parts Discussed in Thread: AWR2944

hello ,i have a question about Doppler DDMA dpu process  about Local Max method from mmwave sdk documentation.Suppose i'm using AWR2944，so i have 4Tx and 4Rx。For Tx, 3 of Tx are Azi Tx and 1 of Tx is Elev Tx，so if i’m doing 64-Point Azi FFT，i‘m using 12 virtual Azi Antenna data to get the 64 Azi FFT result data， the local max method is to peak the max value in the 64 Azi FFT result data . i want to know whether the local max method I described above is correct.If is wrong ,i hope someone can explain the details about local max method.

    Hi,

    From what you have described, it looks like you are referring to just finding the absolute maximum from a distribution. Local maximum is a common algorithm about which you can find more info on the web. For more details about the local max engine on the awr294x device, please refer to the HWA section of the Technical Reference Manual for that device. 

    Regards,
