摘　　要：卫星地面防护范围是指干扰站通过干扰卫星上行链路导致卫星下行通信失效的区域,研究该防护范围具有十分重要的应用价值,结合实际应用场景提出了一种通用的卫星地面防护范围计算方法,首先判断干扰站是否在卫星上行波束覆盖范围内,如果不在,则地面防护范围为零;反之则需要计算卫星下行波束覆盖区域。所提方法适用于任意高度的卫星,且对于干扰站位置、卫星上下行波束宽度以及指向均不限,计算方法简单易行。为证明所提出算法的有效性,将该算法的仿真结果与STK软件的仿真结果进行了对比,同时对误差产生的原因进行了分析,给出了相应减小误差的方法。Satellite ground protection range refers to the area where the jamming station interferes with the satellite uplink resulting in the failure of satellite downlink communication.Studying this protection range has very important military application value.Combined with practical application scenarios,this paper proposes a general calculation method of satellite ground protection range.Firstly,judge whether the jamming station is within the coverage of satellite uplink beam.If not,the ground protection range is zero.Otherwise,the sat⁃ellite downlink beam coverage area needs to be calculated.The method proposed in this paper is suitable for satellites at any height,and is not limited to the position of jamming station,satellite uplink and downlink beam width and direction.The calculation method is simple and easy.In order to prove the effectiveness of the proposed algorithm,simulation results of the algorithm are compared with those of STK software.Also,the causes of errors are analyzed and the corresponding reductions are given.
