Attendees: Richard, Darrel, Fred, Todd, Josh, Geoff, Antonio
Action Items from previous meeting
Josh will send out the NSI farfield data for the average of beam 1 and beam 2. Richard and Fred will compare them with Andrey's farfield result (which was a direct Fourier transform of the beam-combined raw nearfield data)
Josh: We got a response from NSI regarding beam averaging in their software. In most of our previous beam scans, beam 2 was +90 deg from beam 1, which is opposite of what NSI assumes in its processing. But even using scans with the correct beam order, the result does not look right--seeing an extra 20 degrees. Josh will follow up with NSI.
Fred is seeing good (but not perfect) agreement with Andrey's result if he does not correct for the half-pixel shift that should be applied due to having an even number of rows.
Geoff reported some hardware problems with the beam scanning IF system. He is just getting the receiver again today and will proceed with scans with an odd number of rows, and with/without the open-ended waveguide.
