【摘要】 多波束测深系统中经常使用幅度法或相位法来进行海底检测,并且按某种准则来选择,但如果选择错误,可能会带来不可预测的误差。提出了一种多子阵幅度—相位联合检测法,同时利用海底回波信号的幅度和相位信息,综合了幅度法和相位法的优点,不但实现了超宽覆盖,而且改善了检测性能。利用仿真数据和海试数据对此方法进行了验证,得到了较好的结果。更多还原

【Abstract】 Amplitude based methods or phase based methods are usually used in multi-beam bathymetry system and chosen according to some rule,which may bring about unpredictable errors if wrong choose occurs. The article proposes an multi-subarray amplitude-phase united detection method simultaneously using information of amplitude and phase of echo from sea bottom and integrating the merits of the two traditional methods,which not only realizes the super-wide coverage,but also improves the detection performance.By simulating data and experimental data,we have tested the technique and obtained good result.更多还原
