海面舰船目标雷达距离高分辨特性测量

雷达距离高分辨特性,即目标的一维高分辨距离像特性,能够体现目标的形状及结构信息,且易获取,有利于对目标进行准确识别,这已成为目前雷达目标识别领域的一个重要研究方向。开展目标一维高分辨特性研究的一个重要基础是测量,因而通过测量目标的一维高分辨距离像并分析目标特性,对目标识别具有重大理论意义与实际应用价值。基于此,文章利用实验室现有全相参新体制雷达导引头目标测量平台,对海面舰船目标的距离高分辨特性进行了初步实测,获取了海面舰船的米级高分辨距离像,为今后深入开展海面舰船目标识别研究奠定了坚实基础。

Radar HRRP Measurement of Vessels

High resolution range profile (HRRP) can reflect the shape and structure information of the target and is easy toobtain. It is conducive to accurate target recognition, so it has become an important research direction in the field of radartarget recognition. Measurement is an important basis for the study of one-dimensional high-resolution characteristics.Therefore, measuring the one-dimensional HRRPs of targets and analyzing their characteristics have great significanceand practical application value to target recognition. Based on this, in this paper the HRRPs of vessels in the sea surfacewas practically measured with one-meter resolution utilizing the existing full-coherent radar seeker detection platform,which lays a solid foundation for further research on vessel target recognition.
