9. Microwave radiometry has potential for vessel detection 



at relatively short ranges but has no inherent classifica- 

 tion potential. Accordingly^ its overall potential is 

 limited except under special circumstances when completely 

 passive detection is required. 



10. Optical and electrooptical techniques possess inherent 

 classification potential coupled with fair to good detec- 

 tion potential under favorable conditions. Since these 

 techniques are susceptible to degradation by clouds, fog, 

 and sea state returns, they have low potential as primary 

 detection and classification means. Beacons can provide 

 marginal improvement. 



11. Certain techniques examined have a potential to perform 

 functions other than detection and classification that 

 may be useful but not essential to fishery zone enforce- 

 ment. 



12. The USCG is examining many of the techniques included in 

 this survey for their application to its fishing zone en- 

 forcement missions. However, the USCG assessment of the 

 potential of various remote sensing techniques may differ 

 from the assessment given here because USCG planning is con- 

 strained by present resources, presumed budget constraints, 

 and the necessity to consider concurrent performance of 

 other missions such as search and rescue and pollution con- 

 trol, none of which were considered in this survey. Never- 

 theless, on the basis of the results of this survey, we 

 believe that USCG planning would benefit from increased 

 consideration of the potential of over-the-horizon radar, 

 acoustic techniques, and multisource correlation facilities. 

 Data exchange with DoD and the operation of joint-use 

 facilities also appear to have as yet unrealized potential 

 for the support of USCG missions.
