Description
Summary:The methods and tools offered in this paper are based on use of coherent impulse and multifrequency signals in one range of waves (not excluding basically integration's of handling of images in various ranges). Their essential distinctive singularity is the use of spatial (on an angle of a place) and temporal (on delay of signals) distinctions of signals reflected from heterogeneities of stratified mediums. These distinctions are realized by additional spatial-temporal handling of signals on lattices consisting of elementary (in particular, along fuselage) antennas, the phase centers of which are located on a line (vertical, horizontal or sloping), perpendicular to flight direction. Thus the focusing of a system on specific stratums and suppression of signals reflected from the upper stratums of mediums is carried out spatially-temporally. All necessary information about an image of heterogeneities of stratified media, is received thus for one flight of the carrier. The high resolution of an image is reached, as well as in usual synthesized aperture radar (SAR), at the expense of a matched filtering of signals, ensuring synthesis of the aperture.
