摘要: |
为了提高武器在恶劣敌对环境中的生存能力,高抗干扰的嵌入式导航技术越来越受到研究者的关注。在分析卫星/MIMU嵌入式组合导航接收机系统原理的基础上,详细分析了采用MIMU信息辅助卫星接收机跟踪环路,提高多普勒频率估算精度,达到提高系统动态性能和抗干扰性能的要求。然后进一步分析了卫星/MIMU嵌入式组合导航接收机系统抗干扰能力,并以GPS接收机为例,对GPS/MIMU嵌入式导航接收机抗干扰性能进行了仿真。仿真结果表明,卫星/MIMU嵌入式组合导航接收机比一般的卫星接收机跟踪抗干扰性能至少有11dB的提高。 |

Abstract: |
In order to make weapons much more effective in hostile environments, new developments in embedded GNSS/INS integration architectures which offer the possibility of substantial improvements in jamming immunity have aroused great attention from the researchers. This paper introduced the principle and construct of embedded GNSS/MIMU integrated navigation receiver, and presented the method of using MIMU to aid GNSS receiver tracking loop. This technique improved the accuracy of the estimated Doppler frequency, which resulted in higher dynamic and anti-jamming performance. Finally, the paper analyzed anti-jamming performance of embedded GNSS/MIMU integrated navigation receiver. According to the sample of GPS/MIMU, the simulation was done. The simulation results show that anti-jamming performance of embedded GNSS/MIMU integrated navigation receiver has 11dB improvement in comparison with the traditional GNSS receiver. |
