Abstract

Abstract To address the shortcomings of existing methods for rotorcraft searching, positioning, tracking and landing on a ship at sea, a dual-channel LIDAR searching, positioning, tracking and landing system (DCLSPTLS) is proposed in this paper, which utilises the multi-pulse laser echoes accumulation method and the physical phenomenon that the laser reflectivity of the ship deck in the near-infrared band is four orders of magnitude higher than that of the sea surface. The DCLSPTLS searching and positioning model, tracking model and landing model are established, respectively. The searching and positioning model can provide estimates of the azimuth angle, the distance of the ship relative to the rotorcraft and the ship's course. With the above parameters as inputs, the total tracking time and the direction of the rotorcraft tracking speed can be obtained by using the tracking model. The landing model can calculate the pitch and the roll angles of the ship's deck relative to the rotorcraft by using the least squares method and the laser irradiation coordinates. The simulation shows that the DCLSPTLS can realise the functions of rotorcraft searching, positioning, tracking and landing by using the above parameters. To verify the effectiveness of the DCLSPTLS, a functional test is performed using a rotorcraft and a model ship on a lake. The test results are consistent with the results of the simulation.

用于海上船舶旋翼机的双通道激光雷达搜索、定位、跟踪和着陆系统

摘要针对现有旋翼飞机海上搜索、定位、跟踪和着陆方法的不足，本文提出了一种双通道激光雷达搜索、定位和跟踪着陆系统（DCLSPTLS），它利用了多脉冲激光回波积累方法和船舶甲板在近红外波段的激光反射率比海面高四个数量级的物理现象。分别建立了DCLSPTLS搜索定位模型、跟踪模型和着陆模型。搜索和定位模型可以提供方位角、船舶相对于旋翼飞机的距离和船舶航向的估计。以上述参数为输入，通过使用跟踪模型可以获得旋翼机跟踪速度的总跟踪时间和方向。着陆模型可以使用最小二乘法和激光照射坐标来计算船舶甲板相对于旋翼机的俯仰角和滚转角。仿真结果表明，利用上述参数，DCLSPTLS可以实现旋翼飞机的搜索、定位、跟踪和着陆功能。为了验证DCLSPTLS的有效性，在湖面上使用旋翼机和模型船进行了功能测试。测试结果与仿真结果一致。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
