Tb. Jones et Tr. Robinson, COHERENT RADAR (SABRE) STUDIES OF DYNAMICAL PROCESSES IN THE AURORAL E-REGION, Journal of atmospheric and terrestrial physics, 58(6), 1996, pp. 697-705
In the coherent radar technique, backscatter is obtained from plasma i
rregularities even though the radar frequency can greatly exceed the i
onospheric plasma frequency maximum. From the velocity spectrum of the
received signals an estimate of the flow velocity can be obtained and
hence the electric field determined. Information regarding the irregu
larity scattering cross section is obtained from the amplitude of the
backscatter return. Current radar studies of a range of geophysical ph
enomena are presented. In addition, attention is drawn to the problems
of interpreting the radar observations in terms of the underlying geo
physical processes.
