Illumination of air environment using radiation of SW broadcasting stations

The possibility of air objects location in bistatic radars employing as illumination the signals of broadcast SW stations is considered in this paper. The spectrums of illumination signal are investigated experimentally. The requirements to the direct signal blanketing degree for the location assurance at given distances. The possibility of building of bistatic systems complex employing broadcast SW stations and providing location of acquiring object employing the information of Doppler frequency translation of signal receiving from object is considered. The proposed approach can be used in constructing multi-position radars using for illumination the radiation in microwave range of the average orbital navigation satellites GPS and GLONAS, as well as the radiation in ultrashort wave range of low orbital meteorological satellites NOAA.
