Method of detection and identification of one or more remote objects

Claim 1

Method of detection and identification of one or more remote objects by transmitting wave energy towards the object and receiving wave energy reflected from the object as well as processing of information associated with the wave energy received, wherein said processing comprises a number of separate signal parameters pertaining to the wave energy received, said parameters together forming a measured signature relating to the object, and the measured signature is compared with a number of prestored signatures comprising the same separate signal parameters relating to known objects being of interest to the detection and the identification, characterized in that (A) said separate signal parameters are selected to relate to a number of independent observation domains, (B) there is effected a recording of those signatures among the prestored signatures which within predetermined tolerances correspond to the measured signature, (C) subsequent transmission and reception of wave energy is used for updating the separate parameters and thereby the measured signature, (D) the updated measured signature is compared with the recorded restored signatures for updated recording of a smaller number of prestored signatures which within predetermined tolerances correspond to the updated measured signature, (E) and steps (C) and (D) are repeated until there remains a small number of recorded prestored signatures, preferably only one such signature, which defines a small number of objects, preferably only one such object, being of interest.
