UASA Sensor a miniature Synthetic Aperture Sensor for use in real time imaging from Unmanned Aircraft

这个为期6个月的市场验证项目的目的是调查微型传感器的商业可行性，该传感器使用电磁信号和合成孔径数据处理，在任何天气条件下从无人机(UA)实时成像底层地形。这种UASA传感器的主要特点是：·测量范围达1公里，分辨率为&lt；1m·输出峰值功率&lt；250瓦，使用GaN晶体管将电力需求降至最低·重量&lt；2千克，因此可以在一个UA·操作中心频率&lt；2.5 GHz上进行多个单元的工作，因此可以使用高性能、低成本的无线局域网射频组件·数据实时处理，使用高能效处理器，如用于智能手机的SnapDragon S4 CPU。此类传感器的直接用户压力来自荷兰Rijswjk的壳牌勘探总部、挪威的Statoil和意大利的埃尼的员工。该传感器还可以在干涉模式(I模式)下使用，以检测两个或多个后续扫描之间的差异。除了用于导航目的的全天候实时成像外，UAS传感器还可以用于以下检测：·管道中的车辆和人员·海上或地面浮油(I-MODE)·油井附近因从地下储油罐抽油而产生的下沉(I-MODE)·石油管道附近的轨道(I-MODE)我们将探索如何与英国的大学和其他在测量数据处理方面拥有相关专业知识的公司合作。该传感器将用于石油、天然气和矿产勘探工作，代表了这项工作面向商业的方面。社会效益包括实时检测石油泄漏，使补救措施得以实施。经济效益将来自我们使用这种传感器和销售用于勘探和监测工作以及军事应用的传感器。

The aim of this 6 month Proof of Market project is to investigate the commercial feasibility ofa miniature sensor,using electromagnetic signals and synthetic aperture data processing, toimage underlying terrain in any weather conditions, in real time, from an unmanned aircraft(UA). The key features of this UASA sensor are:• range up to 1 km with a resolution of < 1m• output peak power < 250 Watts in which GaN transistors are used to minimise theelectrical power requirement• weight < 2 kg so several units can be carried on one UA• operating centre frequency < 2.5 GHz, so high performance and low cost WLAN RFcomponents can be used• data processing in real time, using energy efficient processors such as theSnapDragon S4 CPU, used in smartphonesDirect user pressure for this type of sensor has come from staff at Shell Exploration HQ inRijswijk in the Netherlands, Statoil in Norway and ENI in Italy. This sensor can also be usedin interferometric mode (I-MODE) to detect differences between two or more successivescans. In addition to all weather imaging in real time for navigation purposes, the UASAsensor could be used in the detection of:• vehicles and people in a pipeline Right of Way• an oil slick at sea, or on the ground (I-MODE)• subsidence near an oil well, as a result of pumping oil from an underground oilreservoir (I-MODE)• tracks near an oil pipeline (I-MODE)We will explore ways in which we could work with universities in the UK and with othercompanies with relevant expertise in the processing of the measured data. This sensor willfind use in oil, gas and mineral exploration work, representing the business oriented aspect ofthis work. Societal benefits include the detection of oil spills in real time, enabling remedialmeasures to implemented.The economic benefits will stem from both our use of this sensor and sales of the sensor foruse in exploration and monitoring work and in military applications.
