METHOD FOR OBTAINING DIGITAL SAMPLES OF RADIO SIGNALS, METHOD FOR PROCESSING A SAMPLE SEARCH QUERY, METHOD OF PROCESSING RADIO SIGNALS, DEVICES AND EQUIPMENT THEREFOR

摘要

The invention relates to a method for obtaining digitized samples from radio signals received on a spectral band determined by a plurality of reception equipment connected to a communication network and sharing a common spatial, temporal and frequency reference frame, said method being characterized in that it comprises the following steps: - transmission (REQ) of a sample search request message to an interrogation server of a database of said network, said base being capable of storing a plurality of digitized samples transmitted by said plurality of communication equipment to said database, a digitized sample being indexed by at least one time index, a geographical location index and a frequency index comprising at least a frequency of reception of the radio signal, said request comprising at least first level search criteria, comprising at least one time criterion, a geographical location criterion and a time frequency criterion; reception (REC) of a response message to said request, comprising digitized samples whose associated indexes satisfy the search criteria of said request.
