Table t-6. Probability of Detection as a Function of Iceberg Size 

 (Type 1 and Type 2 Searches. 27 nm Scale) 



Table E-8 lists the number of 

 SLAR detections over the number 

 of detection opportunities, and the 

 probability of detection (POD), for 

 each SLAR as a function of 

 iceberg size (and for the NORTH- 

 WIND). The two SLARs have a 

 very similar iceberg detection 

 capability. The iceberg POD (for 

 small, medium, and large ice- 

 bergs) for each SLAR is 99 

 percent. 



Table E-9 lists the iceberg POD as 

 a function of lateral range and 

 altitude. Again, both SLARs have 

 a similar iceberg detection capabil- 

 ity at all altitudes and lateral 

 ranges. There is no significant 

 variation in iceberg POD with 

 lateral range or altitude. There is 

 a small decrease in iceberg POD 

 at 8,000 and 1 0,000 feet for the 

 APS-131 SLAR, however. 



These results are similar to the 

 results obtained during 

 BERGSEARCH ■84 and the 1985 

 SLAR Detection Experiment, for 

 the given type of targets and sea 

 conditions.
