Maritime Surveillance with Dual-Polarized Synthetic Aperture Radar

加拿大是一个海洋国家，其经济和总体福祉与海洋密切相关。北极海冰的加速融化将增加加拿大北极地区的船舶交通和资源开发，并延长加拿大东部的冰山季节。利用雷达成像系统，即合成孔径雷达（SAR），可以有效地监测加拿大近海海域，该系统能够全天候、昼夜采集图像。加拿大计划的雷达卫星星座任务（RCM）是一个基于卫星的sar轨道网络，能够在一张图像中成像数千公顷的海洋。随着加拿大准备启动RCM，迫切需要开发操作算法，利用其先进的宽幅成像模式来检测和监测加拿大北极和东海岸海洋中越来越多的船只和冰山。这项研究将进一步加深我们对微波如何从海面、船只和冰山散射的理解，并利用这种理解来设计能够在各种环境条件下运行的探测系统。

Canada is a maritime nation, whose economy and general well-being is closely tied to the sea.The accelerating melt of sea ice in the Arctic will increase ship traffic and resource exploitation in Canada's Arctic, as well as extend the iceberg season in eastern Canada. Monitoring Canada's offshore may be done effectively with a radar imaging system, called a synthetic aperture radar or SAR, capable of collecting images in all weather and day or night. Canada's planned Radarsat Constellation Mission (RCM) is an orbiting network of satellite-based SARs capable of imaging thousands of hectares of ocean in a single image.As Canada prepares for the launch of the RCM, there is an immediate need to develop operational algorithms that utilize its advanced wide-swath imaging modes to detect and monitor the increasing number of ships and icebergs in Canada's Arctic and east coast oceans.This research will further our understanding of how microwaves scatter from the sea surface, as well as from ships and icebergs, and use this understanding to design detection systems capable of operating in a wide variety of environmental conditions.
