为了满足巡航弹对导航系统高精度和强可靠性的要求,提出一种基于光谱红移测速原理的捷联惯导(SINS)/光谱红移(SRS)自主组合导航新方法。在研究光谱红移导航原理的基础上,设计了SINS/SRS自主组合导航系统方案,建立了该组合导航系统的数学模型和算法,并进行了仿真验证。结果表明:提出的SINS/SRS自主组合导航新方法,能利用SRS获得的高精度速度信息对SINS进行校正,有效抑制SINS随时间累积的误差,精度高,可靠性好,能满足巡航弹对导航系统性能的要求。

In order to meet the requirements of cruise missile for high precision and high reliability of navigation system, a new methods for strap-down inertial navigation （SINS）/spectral redshift （SRS） autonomous integrated navigation based on the principles of the spectral redshift velocity measurement was presented. On the basis of studying the principle of spectral redshift navigation, the scheme of SINS/SRS autonomous integrated navigation system was designed, and the mathematical model and algorithm of the integrated navigation system were established, and the simulation was carried out. The results showed that the proposed new method for SINS/SRS autonomous integrated navigation could adjust SINS by using the high precision velocity information obtained by adopting SRS and effectively restrain the error of SINS accumulating over time. And the method had high precision and good reliability, and could meet the requirements of cruise missile for navigation system performance.
