Abstract:

PURPOSE To provide an overview of principles involved in remote sensing of coastal wave data using radar and to summarize several systems that are either fully or quasi-operational. The summaries are intended to aid Corps Districts in selection of remote sensing techniques for coastal wave data collection. BACKGROUND Wave measurement technology has progressed rapidly in the last decade. Remote sensing techniques have advanced from concepts to fully operational systems providing oceanographers and coastal engineers with a wealth of ocean wave information. The measurement of wave characteristics, such as height, length, and direction using electromagnetic EM waves is one of the latest developments in the field of ocean wave studies. Since Crombie 1955 first deduced the physical mechanism responsible for sea scatter of EM energy, numerous approaches have been taken toward producing a viable sensor for measuring ocean wave characteristics. Techniques range from ground-based, high-frequency 5 to 100 MHz coastal radars to spaceborne microwave 0.1 to 100 CHz systems. To give a better appreciation for the information these systems provide, some basic concepts on the interaction of electromagnetic and ocean waves are provided, followed by a brief review of various sensors.
