This monograph describes radar satellite methods and the system of global sensing of the Earth's surface. Various methods of radar surface monitoring are considered: the method of altimeter-profiler, locator-rain meter, method of subsurface sensing, methods of lateral vision and scatterometer. The results of the theory and experimental data on the scattering of radio waves by different types of surfaces are given. Features of satellite radar studies of the sea, continents, glaciers, agricultural lands and forests. For specialists in the field of radiophysics, radar and geophysics, as well as for students, graduate students and engineers - developers of satellite radio monitoring instruments of the Earth . The book can be used as a training manual for the courses "Radar propagation", "Radiolocation" and "Satellite monitoring of the Earth" ..
