Bill sisk's radar blanker manual (.pdf) . ... ipp : Inter Pulse period. ... A radar blanker synchronizes with the ipp of a radar and generates a blanking pulse that is high while the radar rfi is present in our system. ... The observatory has a radar blanker for the airport "FAA" radar and for the iridium satellites (they can be considered radars since they have an 50% uplink, downlink duty cycle). ... The iridium blank output from the iridium supplied box is synced with the uplink cycle. ...

Grazing incidence imaging from 10 to 40 keV Martin Elvis, Daniel G. Fabricant, and Paul Gorenstein The prospects for imaging x rays at energies from 10 to 40 keV with grazing incidence optics are explored. ... The reflectivity of a sample of iridium-coated float glass was measured at small grazing angles (25-5 min of arc) at energies of 8,17, and 26 keV. ... The grazing angle at 30 keV is -10 min of arc. ... At 10-min of arc grazing angle the reflectivity they measured drops sharply beyond 10 keV. ...
