Abstract

In order to reduce the effect of sea clutter on Marine radar

a sea clutter suppression algorithm based on graph feature learning is proposed. The time-frequency transform is used to amplify the dimension of radar echo signal

and based on the idea that the graph structure features can be deeply mined by graph embedding processing

a method of constructing signal node feature vector by graph embedding is presented according to the different structural characteristics of sea clutter and target echo signal in time spectrum. Different from traditional methods such as time domain cancellation and subspace decomposition

this method can be used to implement sea clutter suppression through node classification of different signals in the time spectrum. Simulation and experimental results show that the algorithm can effectively suppress the sea clutter component of radar echo signal

improve the signal to clutter ratio of radar echo signal

and provide a new idea and way for ocean radar to suppress sea clutter.
