  • Background and advantages of GPS based remote sensing are introduced, characteristics of forward scattered GPS signal such as polarization, variation, code delay due to the wave travel distance difference between direct and scattered signal, and the cross-correlation power expansion due to sea surface roughness are discussed in detail. Working principle of the self-developed delay mapping receiver is also presented. The first test flight experiment is done at Tianjin near sea with the delay mapping receiver mounted on an airplane. Analysis shows that results have good agreement to the theory discussed above.
