首先,我们直接引入余弦变换来计算因阶跃关断激发的时域电磁(EM)响应。然后,我们提出了一种基于积分、求和和立方样条插值(ISCSI)方法的新型半解析算法来有效地完成余弦变换。 ISCSI方法将积分分解为部分积分之和,可以通过三次样条插值结合牛顿-莱布尼茨公式来求解。在此基础上,我们应用已知的卷积方法进一步计算机载瞬态电磁测量中任意波形的时域响应。最后,数值测试验证了ISCSI方法比传统的数字滤波器方法更容易实现并且更高效,因为ISCSI方法只需要较少的频率采样量来完成余弦变换。
First, we directly introduce the cosine transform to compute the time-domain electromagnetic (EM) response excited by cause step turnoff. Then, we advance a novel semianalytic algorithm based on integration, summation, and cube spline interpolation (ISCSI) method to efficiently accomplish the cosine transform. The ISCSI method divides the integral into a sum of partial integrals, which can be solved by cube spline interpolation combined with Newton–Leibniz formula. On the basis, we apply a known convolution method to further compute the time-domain response by arbitrarily waveform in airborne transient EM measurement. Finally, numerical tests valid the ISCSI method is easier to implement and more efficient than the traditional digital filter method because the ISCSI method only requires less frequency sampling amount to accomplish the cosine transform.
