| 摘 要： | 以导弹攻防对抗中防御雷达对空间目标的微多普勒频率检测为背景,分析了雷达部署位置对进动目标微多普勒测量值的影响.理论上可证明,当目标的外形尺寸和进动参数确定后,微多普勒频率由进动轴和雷达视线的夹角(平均视线角)唯一决定.从雷达部署在弹道平面内不同区域以及雷达距弹道平面不同距离两方面出发,分析了微多普勒调制带宽随雷达位置的...

| Abstract: | With the purpose of detecting micro-Doppler under the background of missile confrontation, the influence of the radar location was researched. It was proved in theory that when the dimension and the dynamic parameters of the precession target are invariable, the micro-Doppler is only determined by the angle which is between the radar sight and the precession axis called the average sight angle. In the research, the change of the average sight angle and the micro-Doppler bandwidth caused by different locations of radar was studied. At the same time the simulation results in the typical scenarios were shown in figures, which validated the ideas. The conclusion of this paper will benefit how to deploy the radar for detecting ballistic targets. |
