Abstract
A method employed for threat analysis based on the passive-radar principle, using the transmitter in navigation satellites, a plurality of receiving stations, which are operated distributed over wide regions, and at least one evaluation center. The receiving stations act as wake-up sensors, transmit their received signals to at least one evaluation center for comparison with expected signals from each navigation satellite and sensing of a threat. Depending on the result, radar systems are operated on a stationary or mobile basis, can then be used with their higher-quality antenna systems on a three-dimensional basis to obtain more precise details relating to a conspicuous entity and the threat which may possibly originate from it in a possible target region or to a mobile or stationary threatened object, and then to make it possible to decide on any currently required protective or defensive measures.
