由于极区特殊的地理、电磁条件,惯性导航因其自主性和信息完备性使之成为极区导航的首选。然而在考虑全球执行能力时,现有常用的任何一种力学编排方案都不能单独的实现全球导航。通常采用组合编排的方式,这样则不利于惯导算法的全球统一。基于此提出了基于伪地球坐标系的全球导航算法。该方案在全球导航时可以实现惯导算法的内在统一,并可保证物理平台的平稳切换,从而实现平台惯导与捷联惯导系统编排方案的统一。另外,该方案也更方便同其它局部惯导系统进行交互通信,仅不同的参数转换单元是必需的。同时,简单的切换逻辑也可以减小程序设计的复杂度和降低计算机负担。最后通过仿真证明了该算法的可行性。

Optoelectronics Letters 2025年

作者： ZHAO yan LIN Maohua DU Shengzhi TONG Jigang LIU bin HAN Fangfang School of Electrical Engineering and Automation， Tianjin University of Technology Tianjin Key Laboratory for Control Theory and Applications in Complicated Systems Department of Electrical Engineering， Tshwane University of Technology

In order to identify the tilt direction of the self-mixing interference (SMI) signals under weak feedback regime interfered by noise， a deep learning method is proposed. The one-dimensional U-Net (1D U-Net) neural network can discriminate the direction of self-mixing fringes accurately and quickly. For experimental SMI signals， the 1D U-Net can be used for discriminant direction after a one-step normalization. Simulation and experimental results show that the proposed method is suitable for SMI signals with noise within the whole weak feedback regime， and can maintain a high discrimination accuracy for signals interfered by 5dB noise. Combined with fringe counting method， accurate and rapid SMI signal displacement reconstruction can be realized.
