某前视声呐试制过程中的高旁瓣现象的消除

Elimination of High Sidelobe Phenomenon in Trial Production of a Forward-Looking Imaging Sonar

针对某款试制的前视成像声呐初次水池试验过程中出现的成像效果不理想,存在多个旁瓣较高的现象,通过选取合适的试验数据进行处理分析,阐明了该试制样机高旁瓣现象的原因,并通过在算法层面使用阵元失效补偿技术和幅度不一致性校正方法,显著改善了试制样机的成像效果,为下一步的设计改进提供了有益的参考。

In view of the unsatisfactory imaging effect and high sidelobes in the initial pool test of a forward-looking imaging sonar,the reasons for the high sidelobes in the prototype are clarified by choosing appropriate experimental data for processing and analysis.The imaging results are significantly improved by using array failure compensation technology and amplitude inconsistency correction method at the algorithm level,which provides a useful reference for the next design improvement.
