Abstract: High resolution range profile (HRRP) plays an important role in radar target recognition due to its advantages such as easy to acquire, simple to process, and able to represent the shape and structure information of targets. To overcome the "curse of dimensionality" in practical applications, ship target recognition based on HRRP is usually achieved by leveraging extracted recognition features. Therefore, it is necessary to conduct in-depth research on the effectiveness of high resolution range recognition features, so as to reduce the impact of factors such as attitude sensitivity on the accuracy of ship target recognition. On this basis, HRRP measurements with meter-level resolution on three types of vessels are carried out using a high-resolution maritime radar measurement platform based on pulse compression system; structrual domain features such as the scattering center and transform domain features such as the 2nd-order to 5th-order central moments are extracted; the intra-class similarity and the stability of the recognized features are analyzed. The accuracy of conclusions has been verified by means of the target recognition rate, thereby laying a solid foundation for future in-depth research on the recognition of vessel targets at sea.
