lband narrow calibration

nov,2002

     The lband narrow was removed from the dome on 07jan04. This page is for historical signficance. The lband narrow receiver is native circular and covers 1250 to 1530 Mhz.

History  (top)

Gain curves: (top)

fit to gain(az,za) and comparison of pitch, roll, focus loss to measured losses (aug00). (gain curves.)

Misc:  (top)

lband narrow gain curves after horn focus moved (data 21aug02 thru 09sep02). (gain curves)
lbn system performance after horn focus move (21aug02 thru 09sep02).
IFLO compression by the FAA 1350/1330 radars using lbw,lbn (29apr03).
Tsys vs turret position after horn focus changed.
aug02: lbn gain increase when horn moved to correct phase center.
lbn system performance (01sep01 thru 20aug02)
gain curves for lbn (sep01 thru aug02) (gain curves).
SEFD lbn versus frequency across the entire receiver band (14may02)
Compare sefd 01sep01 thru 01may02 lbw,lbn using new cal values (may02)
Sefd, tsys,  and gain  during the daytime  (lbn jun00).
fit to gain(az,za) and comparison of pitch, roll, focus loss to measured losses (aug00). (gain curves.)
lband Sefd, tsys, and gain (night) aug00 (html)
(position switching on flux calibrators using the correlator).
Compare lbw and lbn receivers (Sefd, gain, and tsys  12jul00 daytime).
