A method of radar main lobe jamming detection based on time-frequency-space features
Radar main lobe jamming is an important threat to radar performance.Based on the working prin-ciple of radar jammers,this paper analyzes the different characteristics of active jamming in radar signal,and pro-poses a detection method of radar main lobe jamming based on time-frequency-space characteristics.This method is used to analyze and verify the difference of time-space distribution and time-frequency distribution between jamming and target signal.The methods of spatiotemporal analysis and time-frequency analysis are respectively used to detect and verify different types of interference such as typical remote natural scenes,suppression jam-ming and deception jamming,thus providing a new method for radar active jamming detection.
