COMMENTS FROM REVIEWERS 



This report was prepared in consultation with, and with the 

 assistance of, the U.S. Coast Guard fisheries enforcement office. Since 

 much of the new durveillance technology presented is based on military 

 systems and hardware, OTA requested the U.S. Navy to review and comment 

 on the contents of the report. OTA has received and discussed these 

 comments with the knowledgeable Navy groups. 



The overall comments reflected agreement with the report's 

 conclusions except in the area of capabilities of specific radar and 

 acoustic techniques. While many of these comments are classified and, 

 therefore, not reproduced here, the following summarizes the key points: 



1) Some new research conducted by the Navy in advanced microwave 

 radar indicates that capabilities for detection and classi- 

 fication could be significantly improved from that discussed 

 in this report. It would be desirable to further consider 

 such newly developed military radar technology in future 

 analysis of this subject. 



2) Discussions in the report of acoustics systems for detection 

 and classification do not reflect some of the Navy's 

 experience with advanced systems or capabilities of acoustics 

 experts working in Navy programs. The specific comments 



are classified but they suggest that a better knowledge of 

 advanced acoustic system capabilities would modify some 

 pessimistic conclusions about the usefulness of acoustics 

 and added research may prove fruitful. Future analysis of 

 this subject sould be in cooperation with Navy branches 

 experienced in the field.
