An All Digital Automated Wind Measurement System

In addition to supplying basic meteorological information, vectored wind velocity measurements are essential to the analysis of small caliber ballistic trajectories, optical wave propagation in the lower atmosphere, and wind shears and vorticies. Conventional electromechanical methods, using velocity-to-direct current converters, are often unsatisfactory when integrated into a multisensor array over long path lengths. An all digital system capable of operating as an array over long path lengths has been developed. The system is totally automated. Using complementary metal oxidized semiconductors (CMOS) signal processing remote data acquisition stations, operated under microprocessor control, reliable and accurate asynchronous data transfer has been obtained.
