| 摘要: |
| 为得到测速雷达系统与卫星固定业务地球站在Ku频段共存的条件，以监测中发现的测速雷达实例为依据开展兼容性分析与研究。通过构建干扰模型，讨论了系统间潜在的干扰链路，确定了干扰门限，从多个角度仿真了测速雷达对卫星固定业务地球站的干扰，得到测速雷达等效全向辐射功率为18 dBm时与卫星固定业务地球站之间共存的最大保护距离为1 450 m，最小保护距离为200 m，同时得到了不同发射功率和不同受扰频率下的保护距离。研究成果可为Ku频段静止轨道卫星监测站选址提供必要的技术支撑，还可以为卫星固定业务用户设置地球站提供理论依据。 |

| Abstract: |
| Based on the features of velocity radar discovered in the radio monitoring work,the coexistence conditions between velocity radar and fixed-satellite service in the Ku band are discussed.By formulating the interference model,the potential interference link and the detection threshold is obtained.The simulation of interference between velocity radar and fixed-satellite service indicates that the maximum protected distance is 1 450 m,and the minimum is 200 m for an equivalent isotropically radiated power(EIRP) of 18 dBm of velocity radar.Protection distances under various transmitting power and interfered frequencies are obtained accordingly.The results can not only be used to support site selections of Geostationary Earth Orbit(GEO) satellite monitoring stations in the Ku band,but also provide guidance on Earth station setting for fixed-satellite service users. |
