摘要
基于海上溢油监测需求,自主研发了小型合成孔径雷达(SAR),并基于机载平台开展海上监测试验,进行应用测试。研发的小型SAR工作在C波段,极化方式为VV,质量24kg,可搭载于有人或无人飞行器,对较大面积海域进行实时连续成像,在获取设定分辨率的SAR实时影像的同时,完整记录原始回波信息,可进一步地面处理生成精细影像。2015年8—9月在山东烟台威海近海海域开展了机载小型SAR海洋监测试验,获取了海上目标包括平台、船只、浮筏和海上疑似油膜现象的SAR影像,成像良好。海上试验研究表明,小型SAR可以提供高质量的海面SAR影像数据,为海面目标及油膜的实时监测提供有利支持。
Minitype SAR was developed to realize the near real time monitoring of oil spill,and ex-periment on airborne platform was carried out for application test.The minitype SAR was devel-oped to work on C band,VV polarization,with the weight of 24 kg and finest resolution of 0.5m, and could be aboard on manned and unmanned aerial vehicles.The minitype SAR made the real time and continual imaging of large coverage available,and recorded the original signals for fine imaging further back to ground.The experiment was carried out in August and September of 2015 in Yantai and Weihai offshore waters,with the mini SAR on board the cruiser of State Oceanic Administration.Images of oil rigs,vessels,floating rafts and oil-look-likes were acquired with good quality.It was indicated that the mini SAR provided high quality SAR images,supporting the oil slick detection and marine monitoring.
