II SUMMARY AND CONCLUSIONS 



A, Sununary 



The brief survey reported here involved approximately two man-months 

 of professional effort in the examination of the potential of remote 

 sensing technology to support enforcement of the 200-nmi fishing zone 

 established by Public Law 94-265. The examination focused on determining 

 performance bounds of the following remote-sensing techniques for the 

 detection and classification of foreign fishing vessels: 



• Microwave radar 



• HF over-the-horizon radar 



• Microwave radiometry 



• Electrooptics 



• Electromagnetic intercept 



• Magnetic 



• Acoustic. 



Section IV of the report describes the selection of techniques for 

 examination. 



The enhancement of capability that could be obtained by requiring 

 the use of beacons/transponders on vessels subject to enforcement was 

 also examined, as were the benefits to be gained from combining informa- 

 tion from several sensor systems in a multisource correlation facility. 



The "design target" postulated to permit techniques to be compared 



is a steel hull vessel, 100 ft or longer, equipped with a power plant 



2 

 of 1000 hp or more, exhibiting a radar cross section of 500 m or more 



at microwave frequencies, and equipped with both radio and radar equip- 

 ment. An enforcement environment also was postulated to provide a frame
