国产航天元器件自主可控应用验证方法研究

我国正处于从航天大国成为航天强国的重要阶段，航天元器件自主可控关系到国家制造能力的提升，但由于我国国产元器件发展起步晚、技术差、可靠性不高，因此亟需建立一套较完整的元器件应用验证方法进而加速国产化替代工作。在此通过对元器件生产过程要素评价、功能性能验证、质量可靠性验证、应用适应性验证等多维度综合评估，建成面向产品维度、过程维度、体系维度的系统协调、融合开放的质量能力体系。采用该应用验证体系对国产ADC类器件HWD976进行测试，测试结果SNR为74.3213dB，SINAD为73.6524dB，SFDR为79dB，满足设计之初需求。该方法为支撑后续国产化替代产品的质量保障和应用可靠性评价提供了理论依据，加速推动我国航天装备自主可控目标的实现。

Research on the verification method of autonomous controllable application of Domestic aerospace components

China is in an important stage from a large Aerospace country to a powerful Aerospace country. The autonomy and controllability of aerospace components is related to the improvement of national manufacturing capacity. However, due to the late start of the development of domestic components, poor technology and low reliability, it is urgent to establish a complete set of component application verification methods, so as to accelerate the localization and substitution work. Here, through the multi-dimensional comprehensive evaluation of component production process factors, functional performance verification, quality reliability verification and application adaptability verification, a system coordinated, integrated and open quality capability system oriented to product dimension, process dimension and system dimension is established. The application verification system is used to test the domestic ADC device hwd976. The test results show that the SNR is 74.3213db, SINAD is 73.6524db and SFDR is 79dB, which meets the requirements at the beginning of the design. This method provides a theoretical basis for supporting the quality assurance and application reliability evaluation of subsequent domestic alternative products, and accelerates the realization of the goal of independent control of China''s aerospace equipment.
