Basing of principles and methods of operation of radiometric control and measurement systems

Six basic stages of optimization of radiometric systems, methods of defining the preset components of total error and the choice of principles and methods of measurement are described in succession. The possibility of simultaneous optimization of several stages, turning back to the already passed stages, is shown. It is suggested that components of the total error should be preset as identical ones for methodical, instrument, occasional and representativity errors and the greatest of the components should be decreased first of all. Comparative table for 64 radiometric methods of measurement by 11 indices of the methods quality is presented. 2 refs., 1 tab
