摘要
海水中,舰船辐射电场信号量值较小、频率极低,很容易受到噪声的干扰。针对舰船电场信号的特点,综合测量电极、放大电路、AD转换等考虑,设计了一套基于MSP430系列单片机的舰船电场信号的测量系统。结果表明,该系统在实测中方便地测量了舰船电场信号,具有一定的军事运用价值。
In the sea, the ship ＇S weak electric signal with extremely low frequency is significantly influenced by the noise. Taking into account some factors such as the characteristics of the ship ＇S electric signal, the impact of the metrical electrode, the amplifier and AD, we designs a metrical system for the shaft-rate electric fteld based on MSP430F169. The results show that the system can conveniently measure the ship＇s electric signal.
