高分辨雷达一般采用两套系统，窄带系统作为传统的坐标测量系统，实现目标检测和跟踪；宽带系统实现成像和识别，其在窄、宽带系统之间转换的工作方式会降低雷达的数据率。该文将状态空间方法引入基于宽带一维高分辨距离像的单脉冲雷达的坐标测量，从而实现了宽带系统中的测距、测角，在抑制角闪烁的同时，提高了扩展目标上各散射中心的坐标测量精度。

At present,high-resolution radar employs two systems usually.One is a narrow-band system which realizes measuring coordinates,detecting and tracking,the other is a wide-band system which is used for imaging and recognizing.Due to the fact that switching between the two systems would decrease data rate,a measurement method based on high-resolution range profile is proposed.In this paper,State Space Method(SSM) is introduced to measure coordinates for monopulse radar based on high-resolution range profile.Monte carlo simulation results prove that SSM can increase the measurement precision effectively.
