ZHENG En-ming1,2 SUN Chang-yu1 CHEN Xin-hua1 YU Hua-bing1(1.Institute of Acoustics,Chinese Academy of Science,Beijing,100190,China; 2.University of Chinese Academy of Science,Beijing,100190,China)  
Some scholars suggest that we use autoregressive(AR) model solve the problem that the conventional inverse beam-forming(IBF) is unable to break through the Rayleigh limit,and improve the bear resolution for inverse beam-forming,but the detection performance of this method(AR_IBF) is worse in the practical application.A modified method(MAR_IBF) is advanced for AR_IBF by modifying the AR in this paper,and which has good detection performance and bear resolution.Theory analysis and numerical simulation show that the detection performance of MAR_IBF is improved near 10logN dB(N being number of elements),compared to the detection performance of AR_IBF.
