Description
Technical field
The present invention relates to phased array of microwaves or MIMO array application, such as microwave Imaging Technique, satellite communication and satellite remote sensing
Technology.Application includes anti-terrorism human body safety check microwave imaging, satellite remote sensing microwave imaging.
Background technique
Complete analog radio frequency phased array can be only formed simple beam, therefore its receiver speed in search sweep is slow, noise
Than low, detection range is close.Two-dimensional imaging is done with analog radio frequency phased array simple beam technology, there is sensitivity is low, and imaging time is long etc.
Disadvantage.
Digital multiple beam radio frequency phased-array receiver, can overcome analog radio frequency phased array, can generate two-dimentional letter simultaneously
Number, it is a kind of theoretic ideal phased array reception system.But can only be realized in narrowband systems in practice, the reason for this is that
It is the digital analog converter (ADC) for the high speed for needing to meet that Qwest's sampling theorem in the case where broadband, is difficult to accomplish volume
Small power consumption is low, and therefore, it is difficult to be installed together in narrow space with the receiving channel in the receiver of phased array of microwaves.Separately
Outside due to not doing space filtering in front of the adc, in order not to be disturbed effect of signals, biggish dynamic range and more is needed
Quantization level number, so substantially increase the requirement to ADC design.The ADC of large dynamic range and more quantization level number,
Mean big power consumption.Big power consumption brings biggish current impulse, causes big disturbing pulse voltage, so that
The design of ADC is more difficult.
The power consumption of digital multiple beam radio frequency phased-array receiver causes heat dissipation problem, and may lead when device overheat
Cause device failure.Biggish dynamic range and more quantization level number, while requiring more independently-powered network, it is meant that
More packaging pins, it is desirable that bigger chip package also to the design of system and integrated causes huge challenge.
Another problem is a large amount of image information identification and processing problem.Such as in anti-terrorism human body safety check microwave imaging system
In, the clothing of people is transparent, and can not hide body, the privacy of people is invaded, in addition, a large amount of image information, causes personal monitoring to regard
Feel fatigue.
Summary of the invention
The present invention for the above technical issues, invents a kind of modulus mixing two-dimensional array radio frequency multi-beam intelligence imaging system
System, it is characterised in that when receiving, the Analog Baseband Multibeam synthesis of each receiving unit in receiving array it is complex weighted because
Submatrix unit, according to the output of baseband low pass filters, multiple specific incidence angles signal on the first dimension direction
By multiple specific complex weight factors matrix weights, make reception signal that is multiple while receiving in multiple phases of the first dimension
Temporal synchronization should be just reached up to, parallel Analog Baseband multibeam signals output is formed.The more waves of parallel Analog Baseband
Beam signal exports the parallel digital baseband multibeam signals for being changed into the first dimension through parallel digital to analog converter.First dimension
Parallel digital baseband multibeam signals, by digital signal processor or other hardware, complete two in the second dimension of array
The formation for the multi-beam baseband signal that dimension space can divide.
Above-mentioned this feature, i.e., first do the Multibeam synthesis simulated in the first dimension, then does number in the second dimension again
The Multibeam synthesis of word, eventually forms two-dimensional image, therefore referred to as modulus hybrid radio frequency multi-beam.It is to be solved by this invention another
One technical problem is image recognition and target detection problems, which is characterized in that using artificial intelligence vision neural network to two
Wiki band multi-beam image carries out image recognition and filtering, detects the figure of allergen.Such as anti-terrorism human body safety check microwave at
As since perspective detects, invading the privacy of the person in system, limitation above will receive in application.Using artificial intelligence optic nerve
Network replaces human eye vision to monitor with machine vision, will not invasion of privacy, detection speed can faster more be not in
Visual fatigue.Large nuber of images information in satellite remote sensing imaging system, can also be by artificial intelligence vision neural network to two
Wiki band multi-beam image carries out image recognition and filtering, finds target rapidly, detects the figure of interested allergen.
Application in the target acquisition of flying object is also such.
