F-region electron density and Te / Ti measurements using incoherent scatter power data collected at ALTAIR.==$Annales Geophysicae, 24$==(5), 1333-1342. https://doi.org/10.5194/angeo-24-1333-2006http://hdl.handle.net/20.500.12816/1900The ALTAIR UHF radar was used in an incoherent scatter experiment to observe the low-latitude ionosphere during the Equis 2 rocket campaign. The measurements provided the first high-resolution electron density maps of the low-latitude D- and E-region in the Pacific sector and also extended into the F-region and topside ionosphere. Although the sampling frequency was well below the Nyquist frequency of F-region returns, we were able to estimate Te/Ti ratio and infer unbiased electron density estimates using a regularized inversion technique described here. The technique exploits magnetic aspect angle dependence of ISR cross-section for Te>Ti.application/pdfenginfo:eu-repo/semantics/openAccessIncoherent Scattering RadarF RegionIonospheric Electron DensityRadar AntennasTransmitting Antennasinfo:eu-repo/semantics/articlehttp://purl.org/pe-repo/ocde/ford#1.05.01Annales Geophysicaehttps://doi.org/10.5194/angeo-24-1333-2006
