Abstract
Description
本願は、2019年5月30日に出願された、名称が空中地形測深LiDARシステム及びその方法である米国仮特許出願第62/854571号の優先権を主張するものである。その全ての開示内容が参照により本明細書に組み込まれる。
本発明は、アメリカ陸軍工兵隊によって授与された契約W9127817D0068の下で政府の支援を受けて行われたものである。政府は、本発明において一定の権利を有する。
500mから3000mに移動するには、点密度を維持するために測定レートを6倍増加させる必要がある。これは、レーザーのパルスレートを上げること、レーザーの数を増加させること、及び/又はアレイ型検出器を使用して受信機チャネルの数を増加させることによって達成することができる。受信機チャネルあたりのパルスエネルギーを維持するために、合計レーザーパワーを6倍に増加させる必要がある。これには、従来の検出器とレーザー技術を使用して高高度で深さ方向の透過と点密度を維持するために、数kWのレーザーパワーが必要になる。
