A Time-Domain Method for Shape Reconstruction of a Target with Known Electrical Properties (RESEARCH NOTE) |
|
| چکیده انگلیسی مقاله |
This paper uses a method for shape reconstruction of a 2-D homogeneous object with arbitrary geometry and known electrical properties. In this method, the object is illuminated by a Gaussian pulse, modulated with sinusoidal carrier plane wave and the time domains’ footprint signal due to object presence is used for the shape reconstruction. A nonlinear feedback loop is used to minimize the difference between the measured and calculated signals obtained, by using FDTD at consecutive time windows. The layers of the objects’ shape are reconstructed while the incident plane wave moves over the objects’ surface. Based on the above method, some results are presented for an object with typical geometry. The effect of modulating carrier frequency was investigated for conductivity and dielectric objects. |
