I am investigating the use of both the AD8283 and the Blackfin to process FM-FM-CW radar return signals. Can I demodulate the IF channels in each bessel function channel using polyphase filters or some other way? Show me?
I have moved this to the Blackfin Processors community, as that is your target DSP. Please continue the discussion here.
Can you please clarify your question? I understand that the signal going into the AD8283 is likely the IF signal. The AD8283 performs basic AAF filtering, samples with the ADC then passes these digital signals to the DSP. Are you then looking to implement polyphase filters in the DSP to further demodulate the IF signal?
