Abstract: Nowadays,index weights determining methods of radar emitter target threat assessment are incomplete and non-dynamic.A dynamic and combining weighting assessment method based on analytic hierarchy process(AHP),entropy weight me-thod and technique for order preference by similarity to ideal solution(TOPSIS) model is proposed.First,an index system which includes platform attributes and radar attributes is proposed.Second,the threat subordinating degree functions of qualitive and quantitative attributes are established.Third,attributes are weighted by subjective and objective weights based on AHP and EWM.Fourth,the Poisson reverse distribution is induced for fusing decision information in multiple times.Finally,the threat assessment is obtained based on TOPSIS model.The simulation results show that,the proposed combining weighting dynamic assessment method is more comprehensive,effective,reasonable and actual compared with purely subjective weighting or objective weighting and single-moment method.It can reflect the multi-target threat ranking well and provide a strong basis for the combat command decision.
