Karazin popup.description2 A research object is wideband pulse signals spreading in a homogeneous environment. Purpose of work is construction of the generalized theoretical model by a georadar with emitter - two-dimensional antenna grates on the basis of the experimental measured pulsive descriptions of aerials. To demonstrate possibility of three-dimensional electronic scan-out. To carry out optimization by radiative aerial of the system with the purpose of increase of power of the radiated pulsive signal and improvement of descriptions of both the separate radiated systems and all radiated system on the whole. As a result of implementation of this stage is: - the model of calculation of diagrams of orientation of grates is offered from named above antenna including two-dimensional grates; possibility of three-dimensional scan-out of signal which radiates by a two-dimensional antenna grate is shown, the synthesis of broadening crack aerial is conducted.
