Simulation of Interference Suppression Using Spatial Adaptive Filtering in High-speed Frequency Hopping Data Link
摘要
Abstract
In the complex electromagnetic environment,the data link system is easy to be subject to electromagnetic interference of different interference patterns,which seriously affects the normal work of the data link system,as for the strong electromagnetic interference problems subject to the high speed frequency hopping datalink,the interference suppression technology based on antenna array is studied,and the wideband signal is decomposed into several narrowband signals for processment by using subband spatial adaptive filtering method,the calculation formulas of array output signal-to-noise ratio and array gain direction are derived,and the antenna array gain under broadband noise is simulated and analyzed,the results show that the subband spatial adaptive filtering method can improve the zero defect precision of the jamming direction,and the problems of the zero defect offset and distortion existed during the array antenna reception are improved.关键词
