Three-Dimensional Holographic Imaging Using Single Frequency Microwave Data
Figure 15
Reconstructed images when using one resonant dipole antenna and multiple frequency data: (a) using 8 frequencies with frequency range of 6.2 GHz to 6.9 GHz (100 MHz sampling step) and (b) using 8 frequencies with frequency range of 5.8 GHz to 7.2 GHz (200 MHz sampling step). For this example, the parameters are z1 = 0.5λ, z2 = λ, z3 = 1.5λ, d2 = λ, d3 = 2λ, and s = λ/8. These results are with SNR = 20 dB.
