PREFACE 



This report is published to provide coastal engineers with the 

 results of a project to develop a radar device that will automatically- 

 collect wave direction information at coastal sites. The work was 

 carried out under the coastal hydraulics research program of the U.S. 

 Army Coastal Engineering Research Center (CERC). 



This report was prepared by Mr. Michael G. Mattie, Physicist, and 

 Dr. D. Lee Harris, Chief, Coastal Oceanography Branch, CERC. 



The development of the CERC radar system was accomplished through 

 the advice and support of many people and several organizations. Par- 

 ticular recognition is given to CWO L. Brown of the U.S. Coast Guard 

 Research and Development Center; C. McKinney, Pacific Missile Test 

 Center, who assembled the CERC system; C. Gable who monitored the radar 

 system assembly; and J. Dayton who provided photographic services. 

 Thanks are also extended to Dr. 0. Shemdin of the Jet Propulsion 

 Laboratory for providing the West Coast Experiment data.
