Abstract
This is the final report for the FoT-funded project "3D imaging laser radar in dynamic applications" that was executed 2008-2010. The project has aimed to keep track of the current status and development of 3D imaging laser radar, with focus on target recogni-tion and surveillance applications. We have participated in the international develop-ment in the area, and performed test campaigns, system and performance analysis, signal processing algorithm development and system modeling. We have been keeping track of, and also participated actively, the international devel-opment by co-operations with the leading actors. The project has had co operations with related projects at FOI, and our competence have been transferred to FMV and FM by demonstration projects. We have given support to the FM through direct sup-port actions, seminars and participation in FM studies. We have had bilateral projects with the AFLR (USA) and Fraunhofer (Germany), and a trilateral project with TNO (the Netherlands) and DRDC (Canada). We have also participated actively in two NATO RTO groups. We have reported the international development twice. The first report describes the international development in general and the other is concentrated on new sensors and systems that can perform measurements while the target and/or the sensor are under movement (dynamic applications). We have developed a high performance laser radar system, HiPer, which has very high resolution (mm). The performance of HiPer has been investigated. We have investigated the performance of a short range system called CamCube. In cooperation with AFRL we have analyzed the performance of their top-of-the line laser radar, FLASH-3D. We have taken part in a field campaign, arranged by NATO RTO, where data from various naval objects were collected with laser radar and IR systems. We have performed field campaigns with current top-of-the-line laser radar systems for mapping, and analyzed their performance. Two fundamental pheno-menon have been investigated; the capability to see around corners and the connection between visibility and turbulence at various elevations above the ground surface. We have put a lot of effort into signal processing algorithm development. The targets have been vehicles, land mines, IED:s and marine vessels. The major work has con-cerned target detection using either laser radar data alone or in fusion with data from passive optical sensors. We have tested algorithms for target classification and target re-identification on vessels. We have developed an algorithm for 3D detection and tracking of humans in urban scenarios and we have studied SLAM (simultaneous local-ization and mapping) for indoor applications. FOI-LadarSim, our tool for modeling and simulation of laser radar systems, has been further developed. During these years we have simulated real systems, systems that we want to build and systems currently only present in research laboratories. We have also modeled the correlation between visibility and turbulence for some typical systems.
