Summary
| Description |
English: In this military radar, microwave radiation is transmitted between the source and the reflector by a waveguide. The figure suggests that microwaves leave the box in a circularly symmetric mode (allowing the antenna to rotate), then they are converted to a linear mode, and pass through a flexible stage. Their polarisation is then rotated in a twisted stage and finally they irradiate the parabolic antenna.
Русский: В этом военном радаре микроволновое излучение передаётся от источника к облучателю рефлектора с помощью волноводов. СВЧ-волны выводятся из кабины в круговой поляризации, чтобы обеспечить возможность вращения антенны, затем они преобразуются в линейно поляризованные волны и проходят по гибкому гофрированному прямоугольному волноводу. Затем их поляризация поворачивается в перекрученном жёстком волноводе и в конце они излучаются через рупорный облучатель с диэлектрической линзой на параболическую антенну. |
