Three-Dimensional Holographic Imaging Using Single Frequency Microwave Data
Figure 11
Reconstructed images when using 13 resonant dipole antennas. (a) For this example, the parameters are z1 = λ/8 (0.125λ), z2 = λ/4 (0.25λ), z3 = 3λ/8 (0.375λ), d2 = λ, d3 = 2λ, s = λ/8, and D = 0.25λ. (b) Setup similar to the one presented in Figure 11(a) but when removing the objects at z1 = λ/8 and z3 = 3λ/8 and shifting the objects at z2 = λ/4 toward the aperture by λ/32. In this case, these two objects will have a distance of 3λ/32 from the first imaged line and λ/32 from the second imaged line. These results are with SNR = 20 dB.
