Overview of Anti-Jamming Technology Based on GNSS Single-Antenna Receiver

Abstract

With the deterioration of the electromagnetic environment and the escalation of interference intensity and complexity, especially the introduction of electronic and navigation warfare theory, the anti-interference capability of navigation receivers is demanding. Anti-interference has become a problem that navigation receivers must solve. The single-antenna anti-jamming technology plays a pivotal role in scenarios such as high-precision ranging and resource constraints. This article analyzes and summarizes the main anti-jamming methods and algorithm characteristics based on single antenna, discussing the developing trend of single-antenna anti-jamming technology. It has certain significance for the research and engineering application of anti- jamming technology of GNSS single antenna receiver.
