To improve the ability of least square support vector regression algorithm，a least square wavelet support vector regression model by introducing the Morlet wavelet kernel is presented．The object function and constraint condition are reconstructed by the parameters to be optimized．On the base of it，the model parame— ters are optimized through genetic algorithm．As a result，the model attains the better generalization ability． The least square wavelet support vector regression model is used tO forecast the missile gyroscope’S drift tend— ency．The simulation experiment results indicate the feasibility and validation of the algorithm．So it can provide basis for the gyroscope’S fault prediction and reliability aid decision．
