摘　　要：海上目标检测识别受制于海上目标及海杂波环境特性,基于实测数据认知海上目标的本质特征有利于推进目标检测识别技术进步。针对海上目标散射特性数据不足的问题,升级“雷达对海探测数据共享计划(SDRDSP)”,扩展雷达目标观测的物理维度、提升雷达及辅助数据采集能力,获取不同极化、海况下的海上目标及环境数据,构建海上目标双极化多海况散射特性数据集,并分析其统计分布特性、时间与空间相关性和多普勒谱特性,为数据使用提供支持。后续将推进海上目标类型与数量的持续积累,为海上目标检测识别性能提升和智能化发展提供数据支持。Marine target detection and recognition depend on the characteristics of marine targets and sea clutter.Therefore,understanding the essential features of marine targets based on the measured data is crucial for advancing target detection and recognition technology.To address the issue of insufficient data on the scattering characteristics of marine targets,the Sea-Detecting Radar Data-Sharing Program(SDRDSP)was upgraded to obtain data on marine targets and their environment under different polarizations and sea states.This upgrade expanded the physical dimension of radar target observation and improved radar and auxiliary data acquisition capabilities.Furthermore,a dual-polarized multistate scattering characteristic dataset of marine targets was constructed,and the statistical distribution characteristics,time and space correlation,and Doppler spectrum were analyzed,supporting the data usage.In the future,the types and quantities of maritime targets will continue to accumulate,providing data support for improving marine target detection and recognition performance and intelligence.
