Title:
FEW-SHOT RADAR TARGET RECOGNITION METHOD BASED ON HIERARCHICAL META TRANSFER
Document Type and Number:
WIPO Patent Application WO/2024/082374
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of target recognition, and particularly relates to a few-shot radar target recognition method based on hierarchical meta transfer. In the present invention, features are extracted on the basis of an attention mechanism and hierarchical deep knowledge transfer at a feature level, a sample level and a task level is performed in order to search for an embedding space, such that a sample is close to a category atom of targets of the same category and is away from a category atom of targets of other categories. At the feature level, a feature encoder based on the attention mechanism is designed and global domain-invariant representations of samples are fully mined, such that the problem of domain difference in data distribution of the samples is solved; at the sample level, an atom encoder is designed, and more stable category atoms are generated, such that the influence of outlier samples is avoided; and at the task level, a meta learner is designed, learning experience of training tasks is accumulated and is transferred to a new task, and the capability of cross-task knowledge transfer of a model is developed, such that target recognition based on meta transfer is realized. The target recognition method of the present invention is an intelligent target recognition method.
