On the Design of Multistatic Sonobuoy Fields for Area Search

Abstract : The detection performance of a wide variety of multistatic buoy field layouts is compared using a recently developed method. The analysis applies to large area search; no consideration is given to situations where the search area can be covered with a few sonobuoys. The preferred layout depends on the ratio CR of receiver cost to source cost. At CR 1, the best performing layout is a square grid; near CR = 0.5 it is hexagonal; for CR 0.1, several layouts give comparable performance. These results hold for three different schematic monostatic detection-probability curves, ranging from almost a cookie cutter to a shape with a low-pd tail out to several times the range of the day.
