The invention provides an anti-jamming performance evaluation method and a system for an infrared imaging seeker, comprising the following steps: training a single-core SVR for each core function to obtain a mapping relationship between an input anti-jamming performance index value and an output comprehensive performance evaluation value; and training a single-core SVR for each core function. Acquiring training samples, initializing weights of each training sample, and initializing a regressor F (x) = 0; Regression error is calculated for each single kernel SVR, and the optimal SVR with the smallest regression error is selected. Calculating the weight beta (j) of the optimal learner H (j), and updating the regressor shown in the description; Updating the weights of the training samples according to the weights beta (j) of the optimal learners, and then normalizing the weights beta (j) of all the optimal learners; Returns the regression error calculation until the number of iterations is reached. The invention can obtain comprehensive anti-jamming performance value under the anti-jamming evaluation index system.
