This paper proposes a complementary frequency electromagnetic gyroscope. In this gyroscope, a voltage-controlled oscillator (VCO) is applied to generate complementary frequency signals and the angular rate detection is realized based on a phase-locked loop. The complementary frequency electromagnetic gyroscope can be fully realized by micro-electronic technology, which is beneficial to the miniaturization of the angular rate measurement system and has a wide application prospect. The complementary frequency electromagnetic gyroscope extends the application of the Sagnac effect and replaces the optical signal with the electromagnetic pulse signal. It can make full use of the advantages of microelectronic technology and microwave technology to realize the miniaturization of measuring components and even realize the system on a chip. In this paper, the mathematical model of the complementary frequency electromagnetic gyroscope is established and verified by simulation analysis. Theoretical analysis shows that the measured angular rate is proportional to the relative frequency difference of complementary VCO output. The simulation results indicate that the sensitivity of the complementary frequency gyroscope is 1 × 10⁻⁵ rad/s and is insensitive to noise. When the signal-to-noise ratio is lower than 0 dB, the gyroscope still has good angular rate measurement accuracy.

补频电磁陀螺

本文提出了一种补频电磁陀螺仪。该陀螺仪采用压控振荡器（VCO）产生互补频率信号，基于锁相环实现角速率检测。补频电磁陀螺可以完全通过微电子技术实现，有利于角速率测量系统的小型化，具有广阔的应用前景。补频电磁陀螺扩展了萨格纳克效应的应用，用电磁脉冲信号代替光信号。可以充分利用微电子技术和微波技术的优势，实现测量元件的小型化，甚至实现片上系统。在本文中，建立了补频电磁陀螺的数学模型，并通过仿真分析进行了验证。理论分析表明，测得的角速率与互补VCO输出的相对频率差成正比。仿真结果表明，互补频率陀螺仪的​​灵敏度为 1 × 10⁻⁵ rad/s 且对噪声不敏感。当信噪比低于0 dB时，陀螺仪仍具有良好的角速率测量精度。
