[0023] Steps 1) to 4) are implemented in sequence according to the algorithm of the present invention.
[0024] Step 3 of the algorithm of the present invention is to use support vector machines to classify and train the normalized eigenvectors, wherein the training sample collection method is preferably to collect experimental samples according to the ballistic guidance method of the spiral curve, and this sample selection method can guarantee the training samples The comprehensiveness, diversity and correctness of the training sample classification. Among them, the support vector machine is preferably the SVMPerf classification tool, which has high training efficiency.
[0025] In the algorithm step 4) of the present invention, the constraint relationship between the values of the main lobe confidence threshold α and the side lobe confidence threshold β is α≥β, -2≤α≤2, -2≤β≤2. When the main lobe confidence threshold α is -0.13 and the side lobe confidence threshold β is -0.13, ...
