ABSTRACT
This chapter describes the effectiveness of radar tomography for soil cover research. A comprehensive approach is proposed that combines the application of the OKO-2 ground-penetrating radar (GPR), the conventional method of cross-sectioning applied in soil science, and relevant soil-testing parameters with mobile and laboratory research on the permittivity of hidden soil layers. The increasing requirements of passive microwave and millimeter-wave (MMW)-radar practical applications dictate an increase in efficiency of the system design and its instrumentation, as well as the corresponding signal processing and imaging performance based on the diffraction tomography techniques. There are many practical applications of passive MMW radiometric systems. These systems have gained an increasing interest over the past years due to their imaging capability to see through fog, clouds, drizzle, dry snow, smoke, and other obstacles, where infrared (IR) and optic systems become inefficient.
