rfi mitigation (alfa in general)

Dynamiting towers, radar transmitters:

Historically this has not been a socially acceptable alternative...

(but current social trends may change this...)

Using reference antennas and a cross correlation technique.

F.H. Briggs, J.F. Bell, M.J Kesteven. Requires extra antennas and input devices to sample and or cross correlate the data.

Using the radar blanker for the FAA RADAR.

Reduces the integration time.

Recording full stokes parameters.

Man made rfi is polarized.

Fast dumping (radar pulses are on the order of usecs).
Radar, solar rfi is az,za dependent (depends on source, platform geometry).

If you are going to do drift scans, pick a spot that minimizes the contribution from the rfi background.
