A natural method of high resolution radar target recognition

Automatic target recognition of high-resolution radar is a challenging problem. The key technology is to look for the new feature from the echoes. Because of the complexity of the radar target echoes, to extract an efficient feature is an imperative and difficult task. In this paper, based on the natural measure of chaotic signal, a novel feature extraction method of high resolution radar echoes is proposed. The results of the experiments indicate that the feature is satisfactory. It is practically demonstrated that the feature is very effective and it not only needs little time of the extracting calculation, but also has highly accurate rate of identification.
