摘　　要：介绍了双射频前端GPS遥感延迟映射接收机的设计原理及在海洋风场测量中的应用。设计选用Zarlink公司的射频前端芯片GP2010和相关器芯片GP2021,并采用左旋天线、双射频前端以及开环控制等技术,对海面GPS散射信号相关功率进行测量和记录,为海面风场反演提供数据。给出在天津近海运12飞机上实际飞行试验的输出结果,实验证明了本设计的合理性和可用性。The design theory of double RF front end delay mapping receiver based Zarlink GP2021 and GP2010 for GPS remote sensing and application in sea wind measure are introduced. The technology such as left hand circularly polarized（LHCP） atenna, double RF front end and open-loop control are adopted to measure and record GPS scatter-signal correlative power on sea surface. It provide data for inversion of sea surface wind. Several flight tests are done at near sea of Tianjin with the DMR mounted on an YUN - 12 plane and the test result is given. The test proves the design is rational and usable.
