Radar technology, which was invented and developed for military uses, is now used for many public purposes covering a wide application range, including safe and efficient operation of transport systems, weather forecasting, automobile collision prevention, etc. Radar systems, which are part of the social infrastructure helping support our safe and stable societies, must operate accurately and reliably. In addition, radar radio-waves are a unique resource, and the radar frequency bands are also used by various radio communications equipment, satellite communications and broadcasting, and other radio-wave measurement systems. Consequently, radar systems must meet certain international technology standards to avoid interference with other radio systems. The spread of advanced radar systems requires periodic maintenance tests of radar transmitters and effective measurement methods to assure stable operation and compliance with relevant laws.
This White Paper outlines measuring instruments for testing the basic radio performance of pulse-radar transmissions used mainly for meteorological observations and air traffic-control systems.
