The results of computer simulation show that this method does not require the sampling interval to satisfy the Nyquist sampling criteria and only needs few sampling points to attain very high testing precision,so we can improve the testing speed and effectively reduce the truncation error caused by finite scanning plane on the premise of ensuring t.
计算机模拟结果表明 ,这种方法不要求取样间隔一定要满足奈奎斯特取样准则 ,只需较少的取样点数即可达到很高的测试精度 ,从而能够在保证测试精度的前提下 ,提高测试速度并有效减小由于有限扫描面所引起的截断误差 。
