| Summary: | This paper describes the routine observations scheme implemented for
the Buckland Park medium frequency (BPMF) radar. These observations are
rare among current MF/HF radar observations in that they are made using
a relatively narrow transmit polar diagram. The flexibility of the radar allows
a number of analyses to be performed simultaneously. The analyses described
include the full correlation analysis (FCA), spatial correlation analysis (SCA),
hybrid Doppler interferometry (HDI) and imaging Doppler interferometry (IDI)
for observations of mesospheric dynamics and the temporal and spatial
characteristics of their scatterers, the differential absorption experiment
(DAE) for the estimation of electron densities and collision frequencies, and
meteor analysis for estimation of meteor height, time and angle of arrival
(AOA) distributions. Intercomparisons between wind velocities estimated using
the FCA with SCA, HDI and IDI techniques are presented. The FCA velocities
exhibit the well-known "triangle size effect" (TSE), whereby the wind velocity
is underestimated at smaller antenna spacings. Although the SCA, IDI and HDI
techniques were not applied concurrently, comparisons using FCA as a
reference suggest these techniques produce velocities in good agreement. |
