Abstract:As an important source of radar reflection ,mast will directly affect the stealth performance of overall warship ,so stealth shape optimized design aiming at mast is very significant .Based on the typical radar detection conditions ,an octagon closed-wide mast is taken as the stealth design model . Using the adaptive genetic algorithm ,the mast is optimized with the objective functions which are respectively made by four existing criteria ,including the maximum and average radar cross section (RCS) within the threat area ,the average probability of radar detection and the probability greater than the critical RCS ,and the comparative analyses of optimal mast design in every criterion are put forward .Every optimal mast design in every criterion has a better radar stealth performance ,and the RCS distribution of each optimal design has a certain similarity .The experimental results also indicate that the optimization of the RCS of characteristic angle of mast is invalid .
