参考消息网10月3日报道 港媒称,中国正在研发一种搭载强大激光器的卫星用于反潜战,研究人员希望能够利用它来准确定位海面下500米深的目标。
香港《南华早报》网站10月1日报道称,这是中国不断扩大的深海监测计划最新的组成部分,除了定位潜艇外——大多数潜艇在水下不到500米的深度活动——它还可用于收集全球海洋的数据。
青岛海洋科学与技术试点国家实验室在其网站上称,“观澜号”海洋科学卫星项目于今年5月在该实验室正式启动,旨在加强中国的全球海洋监测活动。该实验室的科学家们正在致力于卫星的总体设计,但是其关键部件正由全国20多个研究机构和高等院校共同研发。
参与该项目的研究人员宋晓泉(音)表示,如果成功,这一技术将使海洋的上层水体变得“近乎透明”。这名科研人员说:“几乎一切都将发生改变。”
半个多世纪以来,海军研究人员一直在尝试使用激光雷达技术来探测潜艇。从理论上讲,当激光束遇到潜艇时,一些脉冲会反弹回来。然后被传感器接收,并通过计算机分析确定目标的位置、速度和三维形状。
但在现实中,激光雷达技术会受到激光设备功率限制以及云、雾、水的浑浊度甚至是鱼和鲸鱼等海洋动物的影响。除此之外,激光束在不同水体间传播时会发生偏斜和散射,从而使得精确计算变得更具挑战性。

Hong Kong media: China's research and development of laser satellite anti-submarine positioning underwater 500 meters submarine

Reference News Network reported on October 3 Hong Kong media said that China is developing a satellite equipped with powerful lasers for anti-submarine warfare, researchers hope to use it to accurately locate the target 500 meters below the sea surface.
Hong Kong's "South China Morning Post" website reported on October 1 that this is the latest component of China's expanding deep-sea monitoring program, in addition to positioning submarines - most submarines are less than 500 meters deep underwater - it also Can be used to collect data from the global ocean.
The Qingdao National Laboratory for Marine Science and Technology Pilots said on its website that the “Guanlan” marine science satellite project was officially launched in May this year to strengthen China's global ocean monitoring activities. The scientists at the lab are working on the overall design of the satellite, but its key components are being developed jointly by more than 20 research institutes and universities across the country.
Song Xiaoquan, a researcher involved in the project, said that if successful, this technology would make the upper waters of the ocean "nearly transparent." The researcher said: "Almost everything will change."
For more than half a century, naval researchers have been experimenting with lidar technology to detect submarines. In theory, when the laser beam encounters a submarine, some pulses will bounce back. It is then received by the sensor and analyzed by computer to determine the position, velocity and three-dimensional shape of the target.
But in reality, laser radar technology will be affected by the power limitations of laser equipment and the turbidity of clouds, fog, water and even marine animals such as fish and whales. In addition, the laser beam deflects and scatters as it travels between different water bodies, making accurate calculations more challenging.

According to public information, such experiments conducted by the United States and the Soviet Union have a maximum depth of detection of less than 100 meters.
In recent years, research projects funded by the National Aeronautics and Space Administration and the Defense Advanced Research Projects Agency (DARPA) have increased the depth of detection. DARPA has developed a device that is mounted on a reconnaissance aircraft that reliably detects targets as small as mines at around 200 meters.
According to reports, China's new devices are capable of generating high-power laser beam pulses of different colors or frequencies, enabling sensitive receivers to obtain more information from water bodies of different depths. These laser beams can be scanned over an area of up to 100 km or concentrated in a space of only 1 km.
It will be used with microwave radars installed on satellites to better identify targets. Although the radar wave cannot penetrate the water body, it can measure the surface movement with extremely high precision - so when the moving submarine produces a small surface disturbance, the radar can tell the satellite where to project the laser beam.
Zhang Tinglu, another researcher involved in the project, said that the main purpose of the satellite is to effectively detect targets in the thermocline (about 100-200 meters below sea level). Although he declined to elaborate on the role of satellites in anti-submarine warfare, the importance of thermocline to submarines is well known. The thermocline can reflect active sonar and other acoustic signals. This means that the submarine may avoid the detection of underwater sound equipment in the thermocline, but it does not escape the "eyes" of the laser beam.
Song Xiaoquan said that the goal of the "Viewing" team is to use all available sensing methods to achieve the deepest possible depth of detection.公开情报,美国和苏联进行的这类实验,最大探测深度不到100米。
近年来,美国国家航空航天局和国防部高级研究项目局(DARPA)资助的研究项目加大了探测深度。DARPA研制了一种安装在侦察机上的装置,可以在200米深度左右可靠地探测到像水雷那么小的目标。
报道称,中国的新装置能够产生不同颜色或频率的高功率激光束脉冲,使敏感接收器能够获取来自不同深度水体的更多信息。这些激光束可以扫描宽达100公里的区域,或者集中在一个仅1公里宽的地方。
它将与安装在卫星上的微波雷达一起使用,以更好地识别目标。虽然雷达波不能穿透水体,但它能够以极高的精度测量水面移动——因此当移动的潜艇产生小的水面扰动时,雷达可以告知卫星应该往哪里投射激光束。
参与该项目的另一名研究人员张廷禄(音)表示,这种卫星的主要目的是实现对温跃层(海面以下100-200米左右)内目标的有效探测。尽管他拒绝详细说明卫星在反潜战中的作用,但温跃层对潜艇的重要性已人尽皆知。温跃层可以反射主动声呐和其他声学信号。这意味着潜艇有可能在温跃层避开水声设备的探测,但却逃不过激光束的“眼睛”。
宋晓泉说,“观澜号”团队的目标是利用所有可用的传感方法来实现尽可能深的探测深度。
