Three-Dimensional Holographic Imaging Using Single Frequency Microwave Data

Figure 8

Reconstructed images when using 13 resonant dipole antennas. For this example, the parameters are z₁ = 0.5λ, z₂ = λ, z₃ = 1.5λ, z₄ = 2λ, d₂ = λ, d₃ = 2λ, d₄ = 2λ, s = λ/8, and D = 0.25λ. At each sampling step, the 7th antenna element is excited and backscattered data is recorded by all antennas. These results are with SNR = 20 dB.
