The potential contribution of each technique is described in terms of 

 inherent technical performance capability, detection range and coverage 

 for a single system, and cost for some defined system capability. 



B. Technique Analysis 



The following analyses of each of the candidate remote sensing 

 techniques identified in Section IV are designed to emphasize those 

 aspects of a given technique and its possible implementations that are 

 most pertinent to its potential to contribute to solution of the enforce- 

 ment problem described in Section III. For this reason, no attempt is 

 made to describe all of the various other uses to which a technique 

 could be (or has been) applied or to pursue the analysis of any technique 

 or mechanization beyond the point at which its potential for this 

 specific application can fairly be evaluated. Thus, some techniques 

 are disposed of fairly quickly when fundamental limitations to potential 

 usefulness exist. To the user of the survey, this simply means that 

 for these techniques no proposed application to the fishing zone enforce- 

 ment problem should seriously be considered unless it promises to over- 

 come these fundamental limitations, which may include not only technical 

 insufficiencies but expected costs that are grossly incommensurate with 

 the performance capability provided. 



For each technique, a brief description of the technique and its 

 significant characteristics is followed by analysis of its probable per- 

 formance capabilities in feasible mechanizations for the performance of 

 functions related to the enforcement mission. Examples of existing or 

 proposed systems with suitable or representative characteristics are 

 cited where possible, and conceptual system characteristics are postu- 

 lated where no suitable system exists. Costs are treated either by 

 citing costs for representative existing systems or by providing engineer- 

 ing estimates of the cost to mechanize a given technique for a particular
