Table E- 12. HC- 130H Operator Object Misinterpretations. 



Number of Incorrect Object Misinterpretations 

 vs Total Number of SLAR Targets 



Table E-12 lists the distribution of 

 the number of incorrect interpreta- 

 tions by the HC-130H SLAR 

 observers over the total number of 

 SLAR targets with altitude and 

 lateral range. This table considers 

 only whether the target was 

 wrongly interpreted as an iceberg 

 or ship. Table E-13 lists the 

 distribution of HC-130H observer 

 misinterpretations of SLAR target 

 size over total number of SLAR 

 targets with altitude and lateral 

 range. Since the HU-25B SLAR 

 observers were inexperienced at 

 interpreting SLAR data, they were 

 not considered. 



Again, no clear conclusions can 

 be made from the data in Tables 

 E-12 and E-13, but some tenden- 

 cies can be seen. Tables E-12 

 and E-13 indicate the HC-130H 

 observers were more likely to 

 misinterpret the type and size of 

 the SLAR target at altitudes 8000 

 feet and higher, and at lateral 

 ranges greater than 1 nm. 



In addition to the data given in 

 Tables E-10 through E-13, the 

 quality of the SLAR imagery from 

 4000 and 6000 feet seemed better 

 than from 8000 or 10,000 feet. 

 The imagery of ships from 4000 

 and 6000 feet was harder with 

 sharp edges, making it easier to 

 differentiate between a ship or an 

 iceberg at these altitudes.
