| 摘 要： | 为解决地面干扰衰减严重、干扰效果不理想的问题,提出了将干扰机置于平流层飞艇的思想。在对GPS伪距测量精度分析的基础上,推导了干扰位置与GPS接收机接收到的干扰功率之间的关系,得到了不同干扰位置下伪距测量方差的数学模型。在给定GPS伪距测量误差的前提下,仿真分析了干扰平台高度与干扰效果之间的关系,结果验证了平流层飞艇载干扰器的高度优势。

| Abstract: | In order to solve the problem of the severe signal attenuation of ground jammers and the imperfect interference effect,an idea of placing the jammer on the stratospheric airship was put forward.Based on the analysis to the GPS pseudo range measurement accuracy,a relationship between the jammer location and the jamming power obtained by GPS receiver was derived.A mathematical model of GPS pseudo range measurement variance at different jammer locations was developed.For given positioning errors,the relationship between the height of interference platform and interference effect was obtained,and the experiment results showed the superiority of stratospheric airship jammer. |
