【摘要】：頻譜彌散(SMSP)干擾是一種專門對(duì)抗線性調(diào)頻脈沖雷達(dá)的有源欺騙干擾。針對(duì)SMSP干擾的抑制問題,該文根據(jù)該干擾的時(shí)頻分布特性,提出一種聯(lián)合時(shí)頻分布和壓縮感知的干擾抑制算法。該方法通過在時(shí)頻域丟棄SMSP干擾信號(hào),保留屬于目標(biāo)信號(hào)的時(shí)頻點(diǎn),并根據(jù)保留的時(shí)頻點(diǎn)與雷達(dá)回波頻譜間的線性關(guān)系,建立壓縮感知最小問題求解模型并利用正交匹配追蹤方法重構(gòu)目標(biāo)信號(hào),實(shí)現(xiàn)對(duì)SMSP干擾的抑制。Monte Carlo仿真結(jié)果驗(yàn)證了該方法的有效性。
[Abstract]:Spectrum dispersion (SMSP) interference is a kind of active deception jamming which is specially against LFM radar. In view of the suppression of SMSP interference, this paper proposes a joint time-frequency distribution and compression sensing interference suppression algorithm based on the time-frequency distribution characteristics of the interference. By this method in the time-frequency domain discarded SMSP interference signal, while preserving frequency belongs to the target signal, and according to the linear relationship between frequency reservation and radar echo spectrum, a compression model aware minimum problem and using the orthogonal matching pursuit method to reconstruct the target signal of SMSP interference suppression. The simulation results of Monte Carlo verify the effectiveness of the method.
