Sound positioning reliability implementing method based on reference point maximum distance

The invention discloses a sound positioning reliability implementing method based on reference point maximum distance. The method includes following steps: designing a sensor array; building a mathematic model; completing time delay estimation; applying a lock phase amplifier to calculate a time difference from a sound source to a reference point; determining coordinates of the sound source; setting a reference point, and verifying accuracy of the sound source. The method has the advantages of high positioning accuracy, low software operand and high anti-noise capacity, and real-time requirements are met while positioning accuracy is ensured. 本发明公开了种基于参考点最大距离的声音定位可信度实施方法，包括如下步骤：设计传声器阵列；建立数学模型；完成时延估计；应用锁相放大器计算声源到达参考点的时间差；确定所测声源坐标；设置参考点，验证所测声源的准确性。本发明技术方案具有定位精度高、软件运算量低、抗噪能力强的特点，在保证定位精度的前提下实现实时要求。
