Abstract
【解決手段】超小型飛行機の電波高度計によって選択された周波数に依存して異なる方向に電波信号を選択的に放出する巻き付け式アンテナ(たとえば、MAVの一部分のまわりに巻き付けられる)の形態を取る。レーダ高度計は、パルス式または周波数変調連続波(FMCW)方式とすることができる。巻き付け式アンテナは、放射要素のグループを含み、少なくとも、各グループは、平均高さが、隣接したグループの平均高さと異なる。さらに、空間の所望のセクターがアンテナから放出される信号によってカバーすることができるように、グループの平均高さによって、どのグループが最も効率的に信号を放出することになるかが決定される。レーダ高度計の中心周波数を制御して、空間の所望のセクターを放射要素に連続的にカバーさせることができる。
