More Information
Summary:The realized microwave reinforced concrete imaging system have the problems of the bad definition of images and incapable of differentiation of multiple steel bar with different depth. It is studied on the parameter setting of microwave frequency range, frequency pace sweep range and sweep pace. Create some models with different number of steel bar, depth and different size of reinforced concrete, Simulation verified the setting of the parameters. Adopt the techniques of normalization, supposed permittivity and threshold filter respectively to improve the imaging algorithm. It is proved that by disposing in multi-aspect, improved the heightening definition of images and the capability of differentiation of multiple steel bar with different depth.
