Synthetic Aperture Radar (SAR) satellite image is first used to monitor dramatically growing green algae near Qingdao coastal in 2008. The system played important role in ensuring Qingdao 2008 Olympic Sailing Competition. Based on imagery statistic analysis, the influences of radar parameter on detection performance are evaluated. A processing method which used in practice is presented. Processing...
There is an increasing performance demand in receiving system of synthetic aperture radar (SAR) in recent days. Different kinds of digital quadrature demodulation (DQD) algorithms are studied and compared in this paper. All DQD algorithms are divided into two classes: with-mixer algorithms and mixer-free algorithms. The condition of mixer-free algorithms is deduced. The performance of different algorithms...
