Abstract :
A `true-attenuation´ estimation algorithm, developed for use on terrestrial and Earth-space propagation paths equipped with simple copolarised range-gated radars, is shown to be computationally twice as fast as previously used algorithms and capable of similar accuracy. The method had been developed and extended to permit the effective elimination of ground-based reflections from objects which are independent of precipitation conditions-especially useful for terrestrial weather radar systems. Possible instability issues are addressed and a two-dimensional rainrate, space and time algorithm is suggested
