描述了小波矩量法的原理
指出了小波矩量法比基本矩量法在计算时间上的优势所在.应用离散小波矩量法对基本矩量法得到的稠密阻抗矩阵稀疏化
从而求解出小波矩量法下的轴向模螺旋天线的电流分布.比较两种方法得出的结果
证明了在保证精度的情况下应用小波矩量法能够大大减少计算时间.
The axially arrayed helix antenna was analyzed with moment method and its current distribution and radiation pattern were studied.The principle of wavelet-moment method was described on the basis of moment method and wavelet analysis.The wavelet-moment method's advantage in computing time over moment method was discussed.The dense impedance matrix was transferred into a rarefied one with discrete wavelet transform method
and the current distribution of the antenna was calculated.It was proved that the application of wavelet-moment method could remarkably reduce the computing time and ensure the accuracy of the calculation results.
