Missile-borne Near-field Radar Coincidence Imaging Using a Uniform Circular Array

Three-Dimensional Imaging with Bistatic Vortex Electromagnetic Wave Radar

“…Figure 6b,c show the range imaging in the monostatic geometry of TR1 and TR2, respectively. According to (10), the information of R m contains the 3-D coordinate information of target and R m = r m + d sin θ m cos ϕ m 2 ; thus, from the expression of the R m , the range result of TR1 and TR2 is listed in Table 1. It is verified by simulation results in Figure 6b,c, respectively.…”

“…In the last ten years, a large number of research results have appeared regarding vortex EM wave imaging technology [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Ref.…”

“…Refs. [10,11] realized that radar coincidence imaging (RCI) depends on spatial phase distribution characteristics of the vortex EM wave in the different modes. The vortex EM wave radar with fractional modes has good anti-noise performance [12,13].…”

“…However, it has no ability to achieve three-dimensional imaging of radar target because of the correlation problem of scattering points. In summary, the above research [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] reconstructs the imaging of radar targets with the monostatic geometry by using UCA. The transmitter is usually set at the center of the UCA, and the receiver uses the UCA in this observation geometry, thus only two-dimensional imaging can be obtained with this monostatic configuration.…”
