Mark, to improve the demodulation signal-to-noise ratio of target.
Further, detecting wave beam is directing radio wave, realizes that the detecting wave beam that is differently directed of radiation specifically can be with
To integrate the detecting wave beam being differently directed using aerial array.Include mutiple antennas in aerial array, utilizes each antenna
The radio signal of middle out of phase carries out the phase mathematics synthesis of different radio electric signal, integrates out different angle of radiation

Survey the scanning accuracy of wave beam.Preset rules, which can be, artificially to be preset or according to specific application environment and detecting wave beam
Scan performance carry out comprehensive assessment after determine.
For example, in the body-sensing environment composed by transmitting terminal and receiving end, receiving end is by receiving transmitting terminal institute spoke
Echo signal is penetrated, determines the location of transmitting terminal, to realize that body-sensing interacts.It receiving end can be towards any side in space locating for it
To irradiance detection wave beam, the radiation scope for detecting wave beam is a sphere.But in actual body-sensing environment, transmitting terminal usually with connect
Receiving end is staggered relatively, and transmitting terminal moves in the space that receiving end faces direction, therefore detects wave beam and swept without comprehensive
It retouches.To reduce power consumed by receiving end irradiance detection wave beam, the radiation scope of detecting wave beam can reduce, specially：Please
Refering to Fig. 3, with receiving end 11 in the three-dimensional system of coordinate of origin, along X-axis ± 45° angle degree direction and along Y-axis ± 45° angle degree

It is simple to penetrate the realization algorithm of the relative position at end this body structure, further increases response speed, to further increase detecting transmitting
Hold the efficiency of locating specific location.Further, since the wavelength of millimeter wave is short, the corresponding wavelength of the frequency range of locating 60G only has
5mm, therefore the corresponding antenna transmitting-receiving structural volume of millimeter wave is smaller, and the receipts of millimeter-wave signal are realized even with aerial array
Hair, the design structure volume of aerial array itself can also tend to be miniaturized.And physical characteristic for millimeter wave itself and
Within the scope of the understanding of communication aspects applied in those skilled in the art, details are not described herein again for it.
The wireless communication control method that the present embodiment is illustrated is applied in body-sensing scene, is issued by detecting different moments
The location of end is penetrated, the line of transmitting terminal present position is the motion profile of transmitting terminal.Due to the scanning speed of detecting wave beam
Very fast (can be microsecond rank) is spent, the movement speed of transmitting terminal is much larger than, therefore can guarantee accurately to obtain transmitting terminal
Motion profile, to realize the input (such as transmitting terminal moves to left and tunes up tv volume etc.) of different control instructions in body-sensing scene.
