Pagination or Media Count:
The results of an expanded study and investigation of the Pulse Pair technique for estimating the first and second moments mean and variance of doppler spectra for radar backscatter from atmospheric phenomena are presented. The theory is extended to include the effects of non-ideal conditions, such as noise, and experimentally verified by extensive performance tests using simulated weather signals with controllable parameters. A proposed experimental model of a real-time digital pulse pair processor is defined and compared with alternate processing techniques. Based on the encouraging results of the study, recommendations are made to carry the theory into practice these include the construction of a real-time digital pulse pair processor with flexible characteristics to gather and reduce data for evaluation while operating with real radars, and the development of additional related theory needed to guide the experimental effort.
