The invention discloses a
radar anti-interference method based on
frequency domain modeling and image
collaboration, and the method comprises the steps: S10, carrying out the preprocessing of an original echo, and finally packaging a preprocessing result into a three-order
tensor form; s20, performing FNO interference
feature extraction and identification, and outputting interference type probability distribution and an interference-to-
signal ratio
estimation value through a de-
wharf; s30, selectively
processing the image, and reconstructing the
histogram into an SAR image in an
equalization manner; s40, evaluating the credibility of the image, and outputting an imaging credibility
score between 0 and 1 through a regression head; s50, generating a credibility-interference combined criterion for judging the reliability of the
radar guidance state; s60, a
loss function is designed, back propagation is carried out through a total
loss function, the model gradient is updated, and
model parameters are optimized; and S70, dynamic anti-interference strategy matching: retrieving candidate anti-interference actions from a preset strategy
library based on the interference types, performing grading and sorting according to complexity, and when the joint risk
score is lower than a set threshold value, activating the optimal high-complexity anti-interference process of the corresponding interference type.
