频谱特性优良的高阶标定脉冲

通过理论分析研究和计算机搜寻得到几种频谱特性优良的高价标定脉冲波形，将其与我国台网广泛使用的阶跃脉冲相比较，可大幅度提高通带短周期段的标定精度，与国外使用的平衡二阶或三阶脉冲比较，具有响主尖波形特征，既可提高通带短周期段标定精度，又不降低通带长周期段精度，此外，具有生成较容易，技术难度适中，便于推广使用等特点。

The excellent high order calibration pulse of the spectrum characteristic

Some excellent high order calibration pulse waveforms of the spectrum characteristic are obtained by theoretical analysing and computer scanning.However we compare them with step pulse generally using at home station network.The calibration preiscion for the short perodic band pass is greatly improved.Meantime,those above mentioned are compared with the second and third order pulse using at abroad,we found that they are of a characterstic of the response waveform.The calibration precision for the band pass of the long period is not only improved,but also its precision is not decrease.On the other hand,they are easy to generate and apply.
