为提高空间目标检测性能，需要分析目标回波模型，研究高速运动目标距离走动补偿方法。针对双基地雷达对空检测过程中可能出现的距离走动问题，建立双基地雷达目标三维模型和回波模型，分析了全过程中目标运动对距离走动的影响，提出了基于分段运动特性的目标检测方法。通过引入两级速度补偿算法，保证参数估计精度的同时提高计算速度。并以空间目标 ISS（International Space Station）为例进行仿真实验，验证算法的有效性和对噪声的鲁棒性。

In order to improve the detection ability of space targets,we need to analyze the echo model and study the solution of range cell migration.In this paper,aiming at the range cell migration of space tar-gets,bistatic radar-target 3D model and echo model are built.The effect of target motion on range cell mi-gration is analyzed.A method based on segment movement characteristics is proposed to eliminate the influ-ence of high speed on range cell migration.A two-stage algorithm of velocity compensation is put forward, which has both high estimation precision and calculation speed.The international space station(ISS)is cho-sen as study obj ect for simulation,which verifies the validity and effectiveness of the proposed method and its good robust property.
