The invention provides a universal intelligent identification method for space
electromagnetic signal types, which takes 23 space
target signal rapid identification functions such as analog modulation signals (AM and FM), composite modulation signals (PCM-FSK-PM) and digital modulation signals (PSK, BPSK, QPSK and the like) as space target electromagnetic signals, and uses an improved DETR network as a target detection classification
algorithm framework. Target extraction and
signal type identification are carried out on space
electromagnetic signal features of various modulation systems, general target detection of a DETR
network model is improved into a special detection model for space electromagnetic signals, 23
training data sets are input twice for an improved DETR network of hierarchical
fine tuning, and compared with the core
advantage of single
signal input training, the method has the advantages that the training efficiency is greatly improved; according to the invention, through multi-class collaborative learning, the
model network has stronger discrimination, generalization and practicability. Finally, a set of integrated, intelligent and high-precision space
electromagnetic signal type intelligent identification universal technology is established, and the method has certain universality in the technical field of
signal processing and analysis.
