Description

phased array identification method and system

Technical Field

The invention relates to the sub-field of intelligent sensors in the information technology, in particular to the active phased array sensing technology, in particular to gesture recognition and moving object recognition of an active phased array, and specifically relates to phased array recognition methods and systems.

Background

An Active electronic phased Array (AESA) detection technology is generally used in military and meteorological fields, and an Active phased Array radar is mainly used for remotely detecting targets such as airplanes, missiles, cloud layers and the like. In these aspects, the product and the application are mature.

The wavelength of MilliMeter Wave (MMW) is usually between 1mm and 10 mm; however, with the development of Integrated Circuit technology, Monolithic Microwave Integrated Circuit (MMIC) technology has enabled wavelengths to extend down to 0.1mm and up to 100 mm. In view of the fact that the wavelength of the millimeter wave suitable for the technical scheme of the invention exceeds the range of 1mm to 10mm, the millimeter wave range in the patent application is 0.1mm to 100 mm.

The development of integrated circuit design and manufacturing technology has realized that a logic core, an analog core and a memory are all designed on the same chips (System on Chip, SoC for short, IP for short), and based on a short-band millimeter wave (for example, with a wavelength of 0.1mm to 3mm), the antenna can be manufactured on an MMIC by using a microstrip antenna, so that micro power consumption, micro volume and micro cost are realized.

At present, the millimeter wave-based active phased array technology is still applied to long-distance detection, for example, over 10km, and the application is military and meteorological. These applications are characterized by high power, long distances, high equipment costs and large volumes. As a short-range application, for example, about 1km, has not been found; especially, the application of the micro-distance in the meter level is not reported as the application of the aspects of gesture recognition, action recognition and the like of micro power consumption, micro volume and micro cost.

The display technology level in human-computer interaction has been greatly improved under the impetus of virtual Reality (VR, Augmented Reality, AR, MediatedReality, Mix Reality, MR) technology. However, how to input human actions, especially gesture action recognition, does not have a good solution at present.

In the field of visible light image recognition, such as apple's patent application "201410198170.5, gesture recognizer with representatives for controlling and modifying gesture recognition", "201210345791.2, gesture recognition system and glasses that can recognize gesture actions"; hua is company's patent application "201310581365.3, gesture recognition method, device and system".

In the infrared recognition, for example, the sony corporation's patent application "201010118390.4, gesture recognition apparatus, gesture recognition method and program" detects gestures using infrared pyroelectric technology, the TCL group's patent application "201210565201.7, three-dimensional gesture recognition apparatus and three-dimensional gesture recognition method" detects gestures using dual infrared cameras, and "201310392905.3, electronic devices and gesture recognition methods".

In ultrasonic recognition, such as patent application '201510151345.1 of the company's co-joined department, ultrasonic-based non-contact gesture recognition method and apparatus therefor ".

In wearable sensor recognition, as in patent application "201510300495.4," radar-based gesture recognition "of wearable device", "201510634055.2, wearable gesture recognition apparatus", "201110384461. X, wireless gesture recognition apparatuses", etc., all implement detection by installing wireless transmission apparatuses on wrists and fingers.

In terms of wireless sensing, Nokia corporation's patent application "201280021975.1, gesture recognition using multiple sensors".

In addition, there are techniques:

patent application No. 201410858259.X, embedded millimeter wave phased array module, 201280026451.1, high performance glass-based 60GHZ/MM wave phased array antenna and manufacturing method thereof by INTEL corporation, patent application No. 201180019783.2 by IBM corporation, phased array millimeter wave imaging technology, 201280037941.1, near field millimeter wave imaging, patent application No. 201380006310.8 by toyota corporation, hybrid radar integrated into a single package, patent application No. 201310341730.3, by midrange 14, millimeter wave active phased array antenna, patent application No. 201210372231.6 by texas instruments corporation, "201080068935.3, terahertz phased array system"; patent application No. 201210393627.9 by sewa university, millimeter wave FMCW two-unit phased array ranging monolithic velocity radar transceiver ", patent application No. 201510347118.6, suspended microstrip antenna array for 60GHZ millimeter wave antenna and antenna thereof by shanghai sanan feno patent application No. 201510590278.3, LTCC-based phased array TR radio frequency component and phased array radar.

Although these patent documents propose good solutions from local view, they do not really propose the active phased array solution with short distance, micro power consumption, micro volume and micro cost, which cannot be applied to the consumer information products such as gesture recognition, and this is a disadvantage of the prior art.
