FAST IMAGING METHOD SUITABLE FOR PASSIVE IMAGING AND ACTIVE IMAGING

WIPO Patent Application WO/2023/045293

A1

A fast imaging method suitable for passive imaging and active imaging and an application thereof in the technical fields of optical imaging, microwave imaging, radar detection, sonar, ultrasonic imaging, and target detection, imaging recognition and wireless communications based on media such as sound, light and electricity. On the basis of the principle of lens imaging, in combination with an electromagnetic field theory, and according to a target signal received by an antenna array, the image field distribution corresponding to a target is obtained by means of amplitude and phase weighting of unit signals by using an efficient parallel algorithm. The method has the advantages of being compatible with both passive imaging and holographic imaging, good in imaging effect, small in calculation amount, low in hardware cost, high in imaging speed, suitable for long-distance imaging and the like; and the method can be widely applied to the fields of optical imaging, microwave imaging, radar detection, sonar, ultrasonic imaging, and target detection, imaging recognition and wireless communications based on media such as sound, light and electricity.
