介绍了频率步进雷达信号利用回波自相关函数形成高分辨距离间隔像的原理，将单脉冲测角原理与高分辨距离间隔像相结合用于对扩展目标的角度测量。对现有的交叉项选大测角方法进行了改进，通过仿真验证了改进后的测角方法可以提高测角精度。最后，通过仿真比较高分辨距离间隔像测角方法和高分辨距离像测角方法，证明了高分辨距离间隔像测角方法在目标运动条件下的优越性。

The principle of forming the high-resolution range separation profile(HRRSP)by the stepped-frequency radar signal and by means of echoes autocorrelation function is introduced. In this paper,the technology of combining the monopulse angle measurement principle with HRRSP is applied to the measurement of target angle. The cross term was modified with AC angle measurement method. The simulation result indicates that the modified angle measurement method can improve angle mea-surement accuracy. The angle measurement method of HRRSP is compared with that of high-resolution range profile(HRRP). The simulations prove that the HRRSP method has a better superiority when a moving target is measured.
