Chapters 5 and 6 are devoted to As to SAR, both azimuthally travelling waves and surface currents become 7.1 SAR INTERFEROMETRY AND REMOTE SENSING OF THE OCEAN SURFACE Earlier Radar remote sensing of the sea surface for the extraction of ocean surface wave fields requires separating wave and non-wave contributions to the sea surface measurement. Conventional methods of extracting wave information from radar measurements of the sea surface rely on filtering the wavenumber-frequency spectrum using the linear dispersion relationship for ocean surface waves.

Ocean current estimated from X-band radar sea surface images, IEEE A method of remotely measuring near-surface ocean currents with a synthetic aperture radar (SAR) is described. The apparatus consists of a single SAR transmitter and two receiving antennas. The phase difference between SAR image scenes obtained from the antennas forms an interferogram that is directly proportional to the surface current. The first field test of this technique against Ocean Surface Winds Description The SeaWinds scatterometer, carried aboard NASA's QuikSCAT satellite, is a microwave radar designed to measure the backscatter related to near-surface wind speed and direction over the oceans. The use of shore-based dekametric-wave radar in the remote sensing of ocean wave energy and surface currents is discussed. The evolution of dekametric The observation and prediction of ocean surface current have attracted more and more concern. Doppler Scatterometer (DopScat) is a new type of radar for ocean surface wind and current field remote sensing. The ocean surface current inversion method of DopScat impacts the measurement accuracy directly. A high-frequency radar remote-sensing system for measuring and mapping near-surface ocean currents in coastal waters has been analyzed and described. A transportable prototype version of the system was designed, constructed, and tested. Remote sensing of ocean surface waves can be difficult using conventional synthetic aperture radar (SAR) techniques, but waves can be observed clearly SAR in the interferometric configuration Ocean.]. We estimate the ocean surface currents using the Doppler Shift on theoretical analysis of ocean surface waves and SAR microwave backscatter.

Vessels, underwater drones, and thousands of floating sensors that drift with the currents. Sensors to identify poorly sampled areas (18.6% of the global ocean surface). Turtles or sharks could also enhance ocean monitoring in other remote and critical hazards such as approaching tsunamis. Remote sensing systems using high-frequency (HF) radio signals backscattered from the ocean surface are capable of mapping surface currents with the necessary spatial and temporal resolution. HF radars rely on Doppler backscatter observations in the HF portion of the electromagnetic Radar remote sensing can also be used to measure ocean currents and radar backscatter from the ocean surface is generally well described The backscattered signal will be modulated the large surface gravity waves and the gravity wave information is derived from the modulation of the backscattered signal. An excellent presentation of the theories of microwave remote sensing of the sea surface is given Plant and Shuler (1980).
