摘要
Abstract
If the suppress jamming pour into the mainlobe of radar antenna , it would severely degenerate the performance of radar . The common ECCM measures of sidelobe have no effect .In this paper , the signal model of mainlobe jamming suppression based on Fast ICA blind source separation algorithm is given first of all .Then the blind source separation algorithm of fast independent com-ponent analysis ( ICA) based on kurtosis in the uniform noise environment is used to separate the high SNR composite signal which is interference and target signal mixed .And the target signal is found out by applying the pulse compression technique between the transmitted target signal and the separated signal at last .Then some simulation experiment is finished to test the validity and to e-valuate the performance of the mainlobe jamming suppression algorithm .The simulation results show the satisfactory validity of al-gorithm in the radar mainlobe jamming suppression and evident superiority in the efficiency of the separation .关键词
