Abstract

Ультразвуковые преобразователи, которые передают/принимают ультразвуковые импульсы с частотами как в низкочастотном (НЧ), так и в высокочастотном (ВЧ) диапазонах, в которых излучающие поверхности указанных ВЧ- и НЧ-диапазонов имеют, по меньшей мере, общую область. Приведено несколько решений для передачи (и приёма) НЧ- и ВЧ-импульсов через одну и ту же поверхность излучения. Решётки и элементы могут быть общего типа, например линейные фазированные решетки, или коммутируемые решётки, или кольцевые решётки, или элементы с разделением как по азимутальному, так и по вертикальному направлениям, например 1,5D, 1,75D и полная 2D решётка. Разделение НЧ- и ВЧ-элементов и апертур решёток также может быть различным.
