摘要: 基于传统正交检测算法在以方波作为激励场源的可控源电磁探测信号幅度与相位提取的不足之处,提出了改进型的正交检测算法。分析了改进型正交检测算法的实现过程,讨论了高通特性大地介质的影响,并针对这些特点,设计了匹配的低通滤波器和降采样率的采样方法,保证了改进型正交检测精度。实测结果表明:改进型正交检测算法具有可行性,且相对于正弦正交检测的幅度误差为0.01%~0.72%,相位误差保证在4°的范围内;相对于方波正交检测算法,检测精度至少提高了一个数量级。改进型正交检测算法在对数据量较大的时域采集信息进行处理时,因无需进行乘法运算、实时性较高、具有较低的硬件要求,且能抑制高通特性大地介质的影响,而在可控源电磁探测中具有良好的应用前景。

Abstract: To overcome the deficiency of traditional quadrature detection algorithm in amplitude and phase extraction of controlled source electromagnetic detection with square-wave excitation source, an improved detection algorithm is proposed. The implementation process of the improved quadrature detection algorithm is analyzed, and the earth medium influence with high-pass properties is discussed. According to these characteristics, the matching low-pass filter and low sampling rate method are designed to ensure the detection precision of the improved algorithm. Experimental results indicate that the amplitude error of the improved algorithm is 0.01% ~ 0.72% compared with the sinusoidal-wave referenced quadrature detection, and the phase error is within 4°. The detection precision is improved at least one order of magnitude compared with the square-wave referenced quadrature detection algorithm. The improved detection algorithm is multiplication-free, in high real-time property, and is of low hardware requirement. Meanwhile, it can restrain the earth medium influence with high-pass properties. So the improved algorithm has good application prospect in controlled source electromagnetic detection.

Key words: information processing technology, controlled source electromagnetic detection, improved quadrature detection algorithm, earth medium with high-pass properties, low sampling rate
