Multiband RESEARCH RADIOKAMERA With mechanical adjustment maximum coefficient RADIOBEZEHOVOSTI

摘要

Multiband research radiokamera mechanical setting maximum coefficient radiobezehovosti.; The invention relates to the field of radio and radar equipment and can be used for dynamic studies of the reflective characteristics of small objects, as well as scale models of objects of big dimensions in compliance with the principle of electrodynamic similarity.; The object of the utility model is to be able to carry out static and dynamic measurement of reflection characteristics of objects in an anechoic zone research radiokamery radiobezehovosti at the maximum possible rate.; To solve this problem, proposed to change the cross-sectional elements in an anechoic radiokamery square, pyramidal elements apply the diaphragm-type square kinked faces in the longitudinal direction and the possibility of mechanical movement of the diaphragm element along the longitudinal axis of symmetry radiokamery on hinges. Pyramids constituting the aperture serves to fix inside radiokamery by hinges made of absorbing materials and located at the corners of the wide base of the pyramids. The main purpose is to provide the best possible hinge anechoic conditions with the working wavelength lambda, which is required for the electrodynamic similarity conditions when changing the zoom factor models of objects to be studied.; The advantages of the proposed multi-band research radiokamery concerns the simplicity of its manufacturing and the lack of overly stringent requirements on the accuracy of the size of holding, since the mechanical adjustment of the relative positions of the diaphragm elements allows to achieve the maximum rate of radiobezehovosti.
