Myakinkov, E.N. Pelinovsky, A.G. Ryndyk, S.A. Shabalin The problems of using robotic systems for survey and registration of tsunami tracks in hard-to-reach places are discussed in this paper. A description of such a complex with good operational characteristics, developed at the Nizhny Novgorod State Technical University n. a. R.E. Alekseeva. A solution that allows to equip an autonomous mobile robotic complex with a sensor of its own production and increase its cross-country abilityis presented. A method for constructing an antenna array is proposed, which allows achieving optimal characteristics in terms of maximum detection range and angular resolution. This result is achieved since the entire geometric aperture of the antenna is «filled» with elements (columns) with a step of half the wavelength. In this case, the placement of the receiving sublattices at the edges of the substrate forms the largest aperture under the conditions of the problem being solved and allows the use of the classical method of diagramming when working in the far zone. An example of constructing an antenna array providing the formation of beams with a width of 5° in the sector of the far-fi eld angles is considered. Application of the proposed solution allows to expand the detection area. Keywords: coastal zone monitoring; maritime disasters; autonomous mobile robot; radar; antenna array.
