The Impact of Sidelobe Suppression in Shift-frequency Jamming against LFM
Sidelobe Suppression (SS) can be found on almost every Linear Frequency Modulated (LFM) pulse radar receiver; Shift-Frequency Jamming (SFJ) is an important method to realize deception jamming using the inherent coupling property between time-delay and frequency-shift of this LFM signal. So, the Inter-Ambiguity Function (IAF) of LFM with SS using normalized parameters including time-delay rate and shift-frequency rate is analyzed. Then the 3:1 cone than weighted, Hamming weighted and cosine square weighted are focused and some parameters related to detection are analyzed. Compared with the none SS, the weighted shift-frequency signal to Jamming loss and the weighted shift-frequency jamming to noise loss are present like M function having the max shift-frequency rate point equal to ± 0.29. And the impact of weighted shift-frequency pulse-width loss are decide by none
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)’.
