In work the method of radar-tracking 3D-mapping subsurface environments from aerospace carriers is offered. The method is based on the offered algorithm of existential processing of multifrequency signals and includes operations of suppression of stirring reflexions from border has undressed "air-ground", synthesis of the aperture and focusing of signals on subsurface the layer located on set depth. As a probing signal use of set of quasimonochromatic fluctuations equidistant frequencies is offered. Prospects of application of such signals for the decision of the given class of problems are caused by their small average capacity, high energy (at the expense of duration), and also with achievements in the field of creation of the modern element base, allowing to provide coherent accumulation (inphase addition) separate components of a multifrequency signal. The estimation of quality of selection subsurface environments is spent. The expediency of use as peak-phase distributions in the aperture of the aerial of new weight windows on the basis of atomic functions which provide selection improvement of quality on 15-27 % in comparison with application of known weight functions is proved. Work is executed within the limits of grants НШ-5708.2008.9 «New methods in some problems acoustooptic, radiophysic and medicine on the basis of atomic functions, wavelets and fractals» and МНТЦ 2866.
