Ship target identification of resonance regions based on RCS
Deng Wei-bo · Systems engineering and electronics · 2008
Ship targets are identified using RCS features of resonance regions.In order to improve the target identification performance,a radar working frequency optimization selection is investigated.A new optimization selection method is given based on the minimum classification error(MCE) rule.A extended nearest neighbor classifier having a rejected threshold is presented based on the multi-type hypothesis testing theory.Target identification simulations indicate that the new frequency optimization method improves the identification performance observably,and the extended nearest neighbor classifier displays good reject ability.
