Information technologies of radar remote mapping and monitoring of extended objects

The analysis of potential opportunities of use of radar technologies of the remote sensing of the earth (RSE) for search of routes of a layer pad of underground communications, such as pipe ducts, and determination of depth of their bedding is presented in the offered article. Three practical technologies of obtaining radar images, depending on options of basing of the equipment of radar-tracking systems of a zemleobzor are considered, namely: aviation or space monostatic; combined with land multistatic aviation or space; mobile and land. It is noted that the problems arising at realization of monostatic systems such as collapse of influence of an ionosphere, restriction of regulations of a radio communication, need of expansion for space of large-size antenna system, it is expedient to solve the combined radar-tracking systems of a zemleobzor. The prospects of use of mobile radar-tracking systems for subsurface sounding from a board of aircraft, multifrequency sounding, and observation of the disguised or covered purposes are shown. The option of development of the mobile radar-tracking system is described; results of a land experiment of the area are given in the mode of radiation of LChM of impulses. The main comparative charac, teristics of the aviation RSA VHFS of range developed in different years and MRLK are provided in article. As an example, results of an experiment on creation of RLI of the land surface at the movement of the car on the bridge are presented.
