Abstract : Three models for ballistic wind measurement error analysis are discussed. These models, which were originally formulated by Donald M. Swingle, are named RAWIN, RADAR, and NAVAID. Each is applicable to a different type of meteorological acquisition system. RAWIN models the case of a balloon-borne radiosonde and ground-based set for radiodirection finding and telemetry data reception. RADAR models the case in which a ground-based radar set tracks an ascending balloon. NAVAID models the case in which radionavigation techniques are used to determine radiosonde position. Expressions for the variance in the East and North components of ballistic wind are obtained in terms of bias and random measurement errors and other parameters. Also, an average error quantity called the component velocity variance is defined. In Volume I each model is described, and the necessary computational expressions are derived. In Volume II the utilization of the associated computer programs on the UNIVAC 1108 at White Sands Missile Range is described. (Author)
