Abstract

The performance of the Tactical Environmental Support System FUR tactical decision aid program UFLR was reported upon previously. In using this code it was assumed that the temperature difference between ship and sea is fixed. In actuality the temperature difference changes with sea state, aspect, cloud cover, and visibility conditions. In this article a simple predictive temperature contrast taking these effects into account is described and validated against experimental data. A modified ThA code UFLRB including this input is compared with observed ranges. The modified procedure shows up to 36% improvement in detection range prediction at night.
