DARPA is focusing on the need to comply with International Regulations for Preventing Collisions at Sea, or COLREGS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>Resource: <\/b><a href=\"https:\/\/www.fbo.gov\/index?s=opportunity&amp;mode=form&amp;id=7daee76fe46aea23ae9e2d19ab2ef4b5&amp;tab=core&amp;_cview=0\" title=\"https:\/\/www.fbo.gov\/index?s=opportunity&amp;mode=form&amp;id=7daee76fe46aea23ae9e2d19ab2ef4b5&amp;tab=core&amp;_cview=0\">Read the RFI<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Currently, ACTUV&#8217;s system for sensing other vessels is based on radar, which provides a &#8217;90 percent solution&#8217; for detecting other ships,&#8221; said a DARPA news release. &#8220;However, radar is less suitable for classification of the type of other vessels, for example determining whether the vessel is a powered vessel or a sailboat. Additionally, one of the requirements of COLREGS is to maintain &#8216; proper lookout by sight and hearing.&#8217;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>Related: <\/b><a

wants sensors as well as image-processing hardware and software that uses passive methods such as electro-optical, or non-radar active sensors such as LIDAR. &#8220;The goal is to develop reliable, robust onboard systems that could detect and track nearby surface vessels and potential navigation hazards, classify those objects&#8217; characteristics and provide input to ACTUV&#8217;s autonomy software to facilitate correct COLREGs behaviors,&#8221; DARPA said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">DARPA is focusing on three areas:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Maritime perception sensors, including &#8220;passive and active imagers in the visible and infrared wavelengths and Class 1 Laser Rangefinder and Flash LIDAR to image ships during day or night in the widest variety of environmental conditions, including haze, fog and rain, over ranges from 4 kilometers to 15 kilometers.&#8221;<\/li><li>Maritime perception software that can detect and classify ships using non-radar sensors.<\/li><li>Classification software that can identify shapes during daytime and by a ship&#8217;s navigation lights.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;We&#8217;re looking for test-ready, multi-sensor approaches that push the boundaries of today&#8217;s automated sensing systems for unmanned surface vessels,&#8221; said DARPA program manager Scott Littlefield. &#8220;Enhancing the ability of these kinds of vessels to sense their environment in all weather and traffic conditions, day or night, would significantly advance our ability to conduct a range of military missions.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ACTUV&#8217;s system for sensing other vessels is based on radar, which
