The 30 MHz coherent scatter backscatter radar in Sao Luis, Brazil has been used for routine two-antenna observations of equatorial E and F region field aligned irregularities since 2002. In 2005, two antenna modules were added to the already existing two modules. These new modules would allow observations with 6 independent interferometric baselines, which then could be used for construction of in-beam radar images similar to those produced at Jicamarca Radio Observatory [e.g. Hysell, 1996]. Despite the low transmitting power and reduced number of baselines, in-beam radar images of F-region scattering structures were successfully constructed with the Sao Luis radar observations. Initial imaging results were used to investigate the horizontal structure of a bottom-type scattering that preceded a fully developed radar plume [Rodrigues et al., 2009]. Here, we examine Sao Luis observations of bottomside radar plumes. Details of the observations and analysis will be presented and the characteristics of the scattering structures seen with this radar will be discussed.
