DTIC ADA186107: Radar Cross Section Reduction of Naval Ships

Until recently, attempts to measure and reduce the radar cross section (RCS) of ships have not been given high priority because it was felt that a meaningful reduction would not be practical. However, advances in computational modeling, as well as British Navy combat experiences at the Falkland Islands and other military developments, strongly indicated a growing necessity to disguise the unique characteristics of combatant ships, to minimize their RCS and reduce their detectability, and to employ electronic countermeasures of reasonable power levels, in order to increase their survivability and thereby allow them to successfully accomplish their missions. Physical mechanisms and theoretical foundation underlying different methods of minimizing the radar cross section of Navy ships are examined for the purpose of reducing surface ship detectability. Also discussed are the statistical description of radar returns from naval ships and the RCS analysis of specific bodies of interest to the Observables Technology Division.
