Embodiment Construction
[0134] figure 1 It is a schematic diagram of the imaging scene of the 3D imaging system based on the NB-IOT signal provided by the embodiment of the present invention. The system is deployed on a tall building, and the imaging area 3 is below the tall building. NB-IOT base station 1 emits electromagnetic waves 360 degrees to the ground. The system obtains an image of an area target by performing signal processing on the electromagnetic wave reflected from the imaging area 3 . This system can also be applied to various other vehicles, low-altitude aircraft, low-altitude unmanned aerial vehicles, etc., including various occasions for civil and military use.

The invention relates to a three-dimensional imaging system based on NB-IOT signal and an implementation method thereof. The system comprises: a signal receiving module that receives a first radio frequency signal transmitted from the NB-IOT base station and second to tenth radio frequency signals returned from the imaging area, and outputs first to tenth signals after amplification, filtering andanalog-digital conversion, wherein the signal receiving module comprises an antenna assembly, wherein the antenna assembly is mounted on the horizontal track and is always in a horizontal moving state when the system works; a communication module that transmits the first to tenth signals output by the signal receiving module to the software module; a coordinate receiving module which is bound with the antenna assembly and is used for acquiring real-time coordinates of the antenna assembly and transmitting the real-time coordinates to the software module; and a software module which comprisesfirst to tenth sub-modules, and carries out a series of processing on the first to tenth signals to obtain a three-dimensional image. According to the three-dimensional imaging system based on NB-IOTsignal and the implementation method thereof, the problems that an existing three-dimensional imaging system is high in price, poor in imaging performance and limited in observation time can be solved.
