摘要:
本文叙述了多波束扫描法孔径合成基阵传感系统的原理。并研究了相位、加权幅度的随机变动,对平均功率图形、阵增益、平均付瓣级以及主瓣声轴方向偏移等影响。本文建立了模拟声全息的数学模型。并将计算机模拟的波束图形特性与随机误差理论分析结果进行了比较,获得基本趋向一致的结论。
Abstract:
This Paper describes Principle of synthetic aperture array system for multibeam scanning method and investigates the influences of radom fluctuations of phase and weight on average power pattern, array gain, average side-lobe level and direction accuracy of main beam axis. The mathematical model simulating beamforming acoustical holography has been built. The eomputer simulated beamforming performaee is compared to some analytical results of random error principle whenever possible for purpose of validation,
