Abstract：Aimed at the problems that the traditional evaluation methods are low in evaluation precision, complex in structure of the model,and is not available in the real-time dynamic threat assessment,an air combat threat assessment method based on least squares support vector machine (LSSVM ) is proposed . Firstly,the threat index of air combat characteristic data is analyzed,and the expert evaluation is used to build the threat assessment sample base .Then,cross hybridization chaos quantum particle swarm optimi-zation(CHCQPSO) algorithm is used to optimize the regularization parameter and kernel function parame-ter in LSSVM,and the results are compared with those of the classical PSO,BP neural networks and mesh models .Finally,the optimized LSSVM model is used to realize the real-time dynamic threat assessment of air combat targets .The simulation results show that the proposed method is high in accuracy and short in time required,thus providing a new idea for evaluating the threat of air combat targets .
