窄带雷达目标特性分析技术在近距离伴飞中的应用

Application of Target Characteristics Analysis of Narrow-band Radar in Accompanying Flight

载人航天任务的近距离伴飞识别实验中,伴星和轨道舱目标相对距离较近,进入设备视场的时间顺序不能确定,导致常用的轨道根数和测站跟踪时序识别法不能对两者加以区分。通过分析目标的物理特性及运动特性,提出了使用雷达散射截面均值及姿态稳定性判别的识别方法。实验结果表明:该方法是近距离伴飞目标识别的有效手段。

Because the distance between the accompanying satellite and the orbital module is very close in space, and the se quence of entering the sight of observation is uncertain, the two targets cannot be discriminated with the common methods such as orbit parameters and sequence identificaiton. Through the analysis of physical and moving character istics of the two targets, an identification method based on mean Radar Cross Section （RCS） and attitude stability de termination is proposed. Result of the experiment shows that the method is effective for target identification in close ac companying flight.
