... Одним из редких, но наиболее интересных явлений, наблюдаемых на радаре НР в Иркутске, является регистрация сигналов с аномально высокой мощностью (когерентных эхо), возникающих во время больших магнитных бурь. Эти сигналы, называемые часто радиоавророй, приходят с боковых лепестков диаграммы направленности антенны. ... Для наблюдения таких сигналов необходимо, чтобы луч антенны был перпендикулярен силовым линиям магнитного поля, то есть мощность отражений обладает сильной ракурсностью. ...
