AWR2243: High doppler peak with no targets

L D
Prodigy 100 points
Part Number: AWR2243
Other Parts Discussed in Thread: TDA2

Tool/software:

Im getting a high peak in the doppler data when looking at ANY scene using any config, even when looking right into an absorber foam panel, almost always at or near range bin 5. Any clue why that is?

    Hi,

    I guess test source is enabled in your configuration. Can you disable the test source and perform the test?

    Regards,

    Hi Samhitha-

    Good guess, but not the case. this is from my config file i used...is there another place that can be turned on with my knowing?:

    test_source_enable  =   0      -- 0: Disable, 1: Enable

    Hi,

    Can you share the whole output log or lua script that you are using?

    It does this with EVERY script, icluding this default from the EVM package:

    Hi,

    Let me review this script and get back to you by mid next week.

    Hi,

    In the lua script that you are using, test source is disabled. When post processing window open, can you click on miscellaneous options and choose remove DC? It might be the case that you are seeing strong signal in the 1st bin.

    Regards,
