Microwave coherent three-dimensional meridian detection method and device and terminal equipment

The invention discloses a microwave coherent three-dimensional meridian detection method and device and terminal equipment, and the method comprises the steps: obtaining a plurality of wave beam microwaves, and controlling the phase of each wave beam microwave through a preset phase controller; performing beam direction control on each beam microwave after phase control and projecting the beam microwave to a preset target body; controlling a preset sensor to receive a plurality of beam microwaves reflected by the target body, and converting the plurality of beam microwaves into electric signals; and combining the electric signals with a preset three-dimensional imaging model to obtain a three-dimensional image, and displaying the three-dimensional image. According to the invention, multi-beam coherent projection can be realized, the positioning precision can be improved, then the phase of each beam microwave is controlled through the preset phase controller, the stability of the center frequency of the multi-
