of reference for the survey in the absence of any information on planned 

 enforcement strategies or mandated levels of enforcement. The environ- 

 ment postulated included the necessity to conduct enforcement activities 

 in any conditions of visibility and precipitation, and in sea states up 

 to 5. A projected maritime traffic density and distribution model was 

 described within which the foreign fishing vessels of interest from the 

 enforcement standpoint are immersed. Section III of the report describes 

 in more detail the survey framework and assumptions summarized above. 



The selected remote sensing techniques were individually examined 

 for their potential to support enforcement in the enforcement environ- 

 ment described in Section III. These analyses are presented in Section V 

 and, for those involving classified information, in Volume Two of the 

 report. Table 2 summarizes the principal survey findings. 



In summary, the survey found that with the exception of magnetic 

 techniques, all of the techniques selected for examination were capable 

 of performing some functions related to pertinent enforcement activities 

 to a degree that offers some potential for supporting enforcement. No 

 single technique was found to be capable, alone and unaided, of perform- 

 ing all of the detection and classification functions that will probably 

 be required, and some have very limited potential. The nature of the 

 principal limitations are indicated in Table 2. In general, most of 

 the techniques selected exhibited the capability to detect the design 

 target in at least some circumstances, with microwave radar operation 

 from aircraft being clearly the most capable and versatile in this re- 

 gard. However, none of the techniques, except certain electrooptical 

 techniques, exhibited any inherent capability to classify detected tar- 

 gets in a way that can contribute to enforcement. However, if the 

 targets sought for detection (foreign fishing vessels) are equipped with 

 beacons, all of the techniques gain some classification capability with 

 the amount of capability depending mainly on the sophistication of the
