A system for detection, localization, and classification of targets, which preferably are located on or close to the surface of the earth, comprises an interrogator, comprising a transmitter, a receiver, and an antenna and is designed for emitting electromagnetic pulses, and one or a plurality of transponders which respond to an emitted pulse by emitting a response signal, each target being provided with at least one transponder, each of which comprise an antenna, an impedance matching network, and a pulse generator. The transponders are designed to emit a response signal as a response to a detected interrogator pulse within a period of time, which is within the time interval between the detected interrogation pulse and the subsequent interrogation pulse. The response signal is coded, so that the code is preferably characteristic of a particular transponder or the category of the target associated with the transponder. The interrogator is designed to detect the response signal and comprises a system processor, which is connected with the navigational system and is, furthermore, connected with a display device. A method for use of the system is also disclosed. |
