The invention discloses a seabed formation measuring method, and belongs to the field of underwater acoustic equipment design and manufacturing. The seabed formation measuring method is applied to a far field condition. Compared with a traditional method that a plurality of positioning sensors are installed on the array, the method has the advantages that the method for estimating the formation through sensor data greatly reduces the complexity of the system and improves the reliability. Under the condition that the far field condition is met, an auxiliary sound source method is used for carrying out formation measurement on a seabed sound array; under the condition that far-field conditions are not met, a traditional auxiliary sound source method is improved by adopting a sound source mirror image compensation method, and the method can more accurately measure and estimate the formation and improve the measurement precision. 本发明公开一种海底阵形测量方法，属于水声设备设计与制造领域。所述海底阵形测量方法应用于远场条件下；较传统的在阵列上面安装多个定位传感器，通过传感器数据估计阵形的方法大大
