Embodiment Construction
[0074] The cylindrical geometry-based three-dimensional microwave imaging method of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, and have no limiting effect on the present invention.
[0075] Such as figure 1 As shown, in the cylindrical coordinate system, the position of the transmitting and receiving antenna is (ρ′, φ′, z′), where ρ′ is the radius of the scanning aperture of the cylinder, φ′∈[0, 2π) is the azimuth of the antenna position, and the direction of φ′ It is defined as the azimuth direction, z' is the height of the antenna position, and the z' direction is defined as the height direction. In the cylindrical coordinate system, the scattering coefficient equation of the target area is I(ρ, φ, z), where ρ is the radius of the target position, φ is the azimuth of the target position, and z ...
