摘要

对于超大型前置分布式相控阵雷达，传统的相控阵雷达标定算法无法应用。因此，本文提出了一种自校准和交叉校准相结合的算法。针对超大型前置分布式相控阵雷达，分析了误差来源，建立了误差模型。然后介绍了自校准和交叉校准技术及其原理。此外，将该方法从单元扩展到相控阵雷达。最后，进行了自相交相位标定仿真实验，结果表明，该算法能够显著提高超大前置分布式相控阵雷达的旁瓣电平。

Self-cross Phase Calibration Method of Oversized Front Distributed Phased Array Radar

For an oversized front distributed phased-array radar, the conventional phased-array radar calibration algorithm cannot be applied. Hence, this paper presents a combination of self- and cross-calibration algorithms. For the oversized front distributed phased-array radar, the error sources are analyzed, and the error model is established. Then, the self- and cross-calibration techniques and their principles are presented. In addition, this method is extended to the phased-array radar from units. Finally, we conducted self-intersecting phase calibration simulation experiments, and the results show that the algorithm can significantly improve the sidelobe level of the oversized front distributed phased-array radar.

期刊介绍： Journal of Radars was founded in 2012 by the Institute of Space and Astronautical Information Innovation of the Chinese Academy of Sciences (formerly the Institute of Electronics) and the China Radar Industry Association (CRIA), which is located in the high-end academic journal and academic exchange platform in the field of radar, and is committed to promoting and leading the scientific and technological development in the field of radar. The journal can publish Chinese papers and English papers, and is now a bimonthly journal. Journal of Radars focuses on theory, originality and foresight, and its scope of coverage mainly includes: radar theory and system, radar signal and data processing technology, radar imaging technology, radar identification and application technology. Journal of Radars has been included in domestic core journals and foreign Scopus, Ei and other databases, and was selected as ‘China's high-quality science and technology journals’, and ranked the first in the category of electronic technology and communication technology in the ‘Chinese Core Journals List (2023 Edition)’.
