【Abstract】 The principle of third-order accumulation method is used to detect fault and estimate the throw of fault. The theory modeling indicates that the method can exactly detect fault and accurately estimate the throw. In addition, it has powerful anti-noise function. The improvement of bi-coherence correlation method is detailed. The practical use shows that the improved method is valid for interpretation of fault.更多还原
