The patent is for a system known as LADAR, which improves laser detection and ranging.

该专利适用于称为 LADAR 的系统，该系统改进了激光检测和测距。

With the increasing diversification of modern detection means, for a single spectrum, such as visible light, infrared light, or for a single type of detector, such as radar, laser detection has long been unable to meet people's needs for " invisibility" .

随着现代探测手段的日益多样化，针对单一光谱，如可见光、红外光，或针对单一类型的探测器，如雷达、激光探测早已不能满足人们对 “隐身”的需求。
