In August/September 2004 the ALTAIR VHF/UHF radar located on Roi-Namur island of the Kwajalein Atoll radar was used to monitor the E- and F-region ionosphere in support of the NASA Equis 2 rocket campaign. The ALTAIR radar operates in two frequency bands centered about 158 MHz and 422 MHz respectively and has a horizon to horizon scanning capability based on mechanical steering of its parabolic reflector. The facility supported the NASA Equis 2 Campaign with a limited number of pulse waveform modes and range resolutions as fine as 150 m. During the September 1-17 window 13 sessions of post-sunset sporadic-E backscatter experiments were conducted. The VHF experiment used 13-baud Barker coded pulses of 1 microsecond baud length while the UHF employed an 88 baud code with the same baud length. The measurements were conducted with an IPP of 10 ms and 2500 range gates were sampled at 60 m intervals beginning at a range of 80 km. The radar beam was typically scanned in the zonal plane from west to east while maintaining a perpendicular orientation to the geomagnetic field in E-region heights. Coherent backscatter response observed at both frequencies (VHF and UHF) was most intense in the period immediately after sunset, although sporadic episodes of unstable layers were observed occasionally as late as local midnight. Absolute cross sections of UHF and VHF echoes from post-sunset E-region irregularities will be presented.
