摘要：
本发明公开了一种电场传感器温度漂移及时间漂移的实时差分补偿方法，包括：(1)所述电场传感器包括至少一个电场测量单元和至少一个电场参比单元，所述参比单元用于对所述电场传感器的温度漂移和时间漂移进行补偿；(2)补偿主要是通过对所述电场测量单元的输出信号与所述电场参比单元的输出信号进行差分，计算所述电场传感器的差分输出；(3)根据所述电场传感器的差分输出及其校准参数，推算被测电场的大小。本发明的目的是为解决电场传感器实际应用中温度引起的温度漂移和时间漂移这一关键问题，提供一种有效的、使用方便的漂移实时补偿方法。
摘要（英）：

The invention discloses a temperature drift and time drift real-time difference compensation method for an electric-field sensor. The method includes the following steps: (1) the electric-field sensor includes at least one electric-field measurement unit and at least one electric-field reference unit. The reference unit is used for compensating for the temperature drift and time drift of the electric-field sensor. (2) the compensation is performed mainly through performing difference on output signals of the electric-field measurement unit and output signals of the electric-field reference unit to calculate difference output of the electric-field sensor; (3) according to the difference output and calibration parameters of the electric-field sensor, the intensity of a tested electric field is calculated. The temperature drift and time drift real-time difference compensation method for the electric-field sensor aims at solving a key problem of temperature drift and time drift caused by temperature in the practical application of an electric-field sensor. Therefore, a drift real-time compensation method which is effective and convenient to use is provided.
