Several of these groups have organized scintillation measurement campaigns at low and high latitudes. Some characteristic results obtained from the measured data are presented. The paper also addresses the modeling activities: four models, based on phase screen techniques, with different options and application domains are detailed. Finally some new trends for research topics are given. This includes the wavelet analysis, the high latitudes analysis, the construction of scintillation maps and the mitigation techniques.662 1252 - PublicationOpen AccessROSE: a high performance oblique ionosonde providing new opportunities for ionospheric research(1994-05)
; ; ;Arthur, P. C.; Radio Propagation Group, Defence Research Agency, Malvern, Worcestershire, U.K. ;Cannon, P. S.; Radio Propagation Group, Defence Research Agency, Malvern, Worcestershire, U.K.; A high quality high frequency (HF) oblique ionosonde has been developed for use in propagation research and associated studies of the ionosphere. The ionosonde is known as ROSE (radio oblique sounding equipment) and requires the connection of a specially designed enhancement to a commercially available chirp sounder receiver (RCS-5) manufactured by the BR Corporation in the U.S.A. Two important features are brought about by the addition of this enhancement. Firstly, an increase in the resolution of an ionogram by a factor of approximatety three. This allows the fine structure in the ionospheric returns to be detected. Secondly, colour coding of the ionogram according to the amplitude of the received signal. Detailed mode amplitude information and comparisons of the relative strengths of propagating modes can be achieved through this. Additional features which are provided include display handling, data storage and off-line analytical facilities. This paper describes the system architecture of ROSE, its main features and its application to ionospheric research.248 512
