Abstract

The invention provides a phased array identification method and system to realize object motion recognition including gesture recognition, automotive anti-collision recognition, collision avoidance and anti-attack recognition of an unmanned aerial vehicle, and smart missile and ship collision prevention recognition. The system is composed of a phased array antenna array, a phased array T / R assembly array and a signal processing system. A phased array millimeter wave is emitted and a millimeter wave reflected by a detected object is received; and calculation is carried out to determine a spacecoordinate of the detected object. The calculation includes one based on an artificial intelligence algorithm and is implemented by steps of target recognition, correction, searching, tracking, and gazing and the like. The signal processing system includes a Von's computer, a non-Von's computer, a neural network, and an artificial intelligence system. The phased array identification system can bemanufactured into a two-in-one MMIC chip and a three-in-one SoC MMIC chip.

Description

technical field [0001] The present invention relates to the subfield of intelligent sensors in information technology, in particular to active phased array sensing technology, in particular to active phased array gesture recognition and moving object recognition, and specifically to a phased array recognition method and system. Background technique [0002] Active Electronically Scanned Array (AESA) detection technology is usually used in military and meteorological aspects. Active Electronically Scanned Array radar is mainly used for long-distance detection of aircraft, missiles, clouds and other targets. In these aspects, both products and applications are relatively mature. [0003] The wavelength of millimeter wave (MilliMeter Wave, MMW for short) is usually between 1mm and 10mm; however, with the development of integrated circuit technology, the process and technology of monolithic microwave integrated circuit (MMIC for short) have made The wavelength extends down to 0...
