摘要： 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.

摘要： A new method has been developed as an attempt to improve speed and robustness of existing ISAR classification methods. The new method produces a set of silhouettes of possible models in a 3D model database. The set of silhouettes of each model views the model from various viewing angles, as the target dimensions will vary as it is viewed from different angles. The silhouettes are stored as a training set. Classification is done by comparing the silhouette of the target with the set of silhouettes in the training set. The silhouettes are calculated prior to the silhouette matching.

摘要： A system and method for the detection and measurement of atmospheric air movement irregularities such as wind velocity vector, clear air turbulence, aircraft induced vorteces and turbulence, by means of electromagnetic waves. An air volume (10) under investigation is illuminated by a transmitter (1, 1A, 1B) with a beam of coherent electromagnetic energy (1E), and a resulting wave field (2E) is received and subsequently coherently demodulated and processed in process means to derive information on the existence of the said atmospheric irregularities and furthermore to give specific measurements of related parameters. At least one receiver (2, 2A, 2B) for said resulting wave field (2E), which is due to scattering in said air volume (10), is positioned at a bistatic location having a selected distance (2R) from said transmitter (1, 1A, 1B). Said electromagnetic energy (1E) is transmitted at microwave frequencies in a concentrated beam. Transmitter and receiver antennas (1A, 1B, 2A, 2B), respectively, are directed so as to cover said air volume (10) with a scattering angle ( THETA ) chosen to have such a (low) value that scattering from atmospheric irregularities in said air volume (10) has a higher power than noise sources in the system.
