Hi
We are working on a phase interferometer direction finding application using
X310 and one twinRx. Our basic model is to use five channel broadband DF
antenna with a switching matrix which converts RF from 5 channels to to 2
Channels. So far we able to phase aligned all the channels and calculate angle
of arrival for instantaneous bandwidth (5MHz) . Our final requirement is to
process 40MHz (dual Channel) or 80MHz (signle channel),Is it possible to
process using 10G PCI card and some high end CPU. With 1G Ethernet I should be
able to achieve 10MHz BW for dual channel (20MHz for single channel) but for
10MHz i am getting error of time alignment of samples. At present we are
taking IQ samples and doing FFT in CPU and calculating AOA.
Is it possible to do FFT and calculate angle using phase interferometer
algorithm in less than 2ms for 40MHz BW (dual channel) with 4K FFT.

Hello Arun:
The gr-doa OOT was tested with UHD 3.10.1.0 and GNU Radio 3.7.10.1, but it
should work with the latest releases, UHD 3.13.0.2 and GNU Radio 3.7.13.4.
It uses the default FPGA image that comes with whichever version of UHD that
you're using. It does not require any custom or special FPGA image.
Please let me know if you have any further questions.

information which FPGA image was used for gr-DOA demo application?
