Microwave visualization of layered dielectric half-space using range profiling of phase

A novel method of subsurface radar data processing based on independent determination and representation of amplitude and phase profiles is described. As the phase of the reflected signal depends on dielectric properties of buried target, the proposed technique is suitable for target discrimination. The amplitude and phase information is merged in the common image by governing intensity and color of the image. The amplitude profile of the reflected signal is obtained using a standard inverse Fourier transform of the frequency domain data whereas the phase profile associated with the reflection act at the given depth is derived using a special data processing technique. Some numerical and experimental examples illustrating the method performance are presented.
