摘要 提出了将契比雪夫加权应用于被动合成孔径处理算法。被动合成孔径技术对小孔径基阵沿直线运动接收到的信号进行合成处理,从而达到虚拟大孔径基阵方位分辨力效果。将契比雪夫加权应用于线阵合成孔径前后波束图的指向性研究,对主瓣宽度变化予以合理解释。理论分析结合仿真验证表明,被动合成孔径处理算法应用契比雪夫加权可以在给定的旁瓣高度要求下获得等旁瓣级,等旁瓣级下可提高对弱目标信号的检测分辨能力。 Passive synthetic aperture processing algorithm application in Chebyshev weighting is proposed. The technology of passive synthetically aperture is for synthetically processing the received signal of small aperture aray along the linear motion, in order to achieve the orientation resolution effects of the virtual large aperture array. Based on the use of Chebyshew weighting for the linear array synthetic aperture directional beam pattern, the mainlobe width change is justified. Through theoretical analysis and simulation on passive synthetic aperture processing algorithm application in Chebyshev weighting, the equivalent sidelobe level in condition of fixed sidelobe height can be attained, and it is apparent to improve the ability to distinguish the weak target signal under equivalent sidelobe level.
