<p>A method of detecting remote objects by transmitting wave energy and receiving wave energy reflected from the object, and processing of information in the wave energy received. The processing comprises separate signal parameters pertaining to the wave energy received, said parameters forming a measured signature of the object. The measured signature is compared with a number of prestored signatures comprising the same separate signal parameters relating to known objects of interest. A recording is made of which prestored signatures correspond to the measured signature within predetermined tolerances. Subsequent transmission and reception of wave energy is used for updating the separate parameters and the measured signature. The updated measured signature is compared with the recorded prestored signatures for updated recording of a smaller number of prestored signatures corresponding to the updated measured signature within predetermined tolerances. The latter two steps are repeated until there remains a small number of recorded prestored signatures which define a small number of objects being of interest. The method is primarily intended for radar systems.</p> |
