Abstract : Use of radar and multiple phototheodolites for obtaining wind velocity data has become common at WSMR in recent years. These systems yield position and velocity data at a much faster rate than conventional theodolite systems. Since the limitations of data obtained with radar and phototheodolites are not well known to the meteorologist, this study was undertaken to investigate some of these problems from a meteorologist's viewpoint. Several fundamental problems were investigated. Some are due to the geometry of the trackers relative to the balloon and others to the mathematics of processing the basic data. It was found, for instance, that estimates of the position components (x,y,z) are affected by the mathematics of transforming from the basic observations range, azimuth and elevations. It was also found that there are advantages to using the range, azimuth and elevation (R,A,E) coordinate system in performing a dynamic evaluation of the tracking system. Finally, care must be exercised in performing a dynamic evaluation or a strong possibility of underrating the system can result due to geometry alone. (Author)
