摘要：
Low probability of intercept (LPI) radar has become a key technology system or working mode of radar equipment in the new era. The study of LPI radar signal modulation recognition and parameter estimation methods has become a hot spot in the field of radar counter reconnaissance. This paper firstly analyzes the intra-pulse characteristics of several typical LPI radar signals, sorts out the traditional and mainstream methods of LPI radar signal modulation recognition and parameter estimation, and explains their principles, advantages, disadvantages and research status. Finally, the remaining problems of existing LPI radar signal modulation recognition and parameter estimation methods are summarized, and their future development trends are also pointed out, aiming to provide some reference for future scholars' research. © 2024 Chinese Institute of Electronics.
