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.

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. --Neel Pandeya On 23 October 2018 at 13:35, Arun kumar Verma via USRP-users <usrp-users@lists.ettus.com> wrote: Hi I am working on Direction of Arrival application using X310, just need information which FPGA image was used for gr-DOA demo application?
