摘要
对利用带电目标自身所产生的静电场来获取目标信息并进行目标探测的被动式静电探测系统(包括探头、放大电路、滤波电路、进入采集芯片前的信号调理电路、抓频电路和RS232串口通讯电路等几个部分)进行了研究,并对探测系统的性能进行了实验分析,结果表明,所设计的电路能够满足预期的设计要求.
The passive electrostatic detection system, based on the measurement of the electrostatic field produced by the moving target and the detection target thereafter, is investigated in this paper. The system includes an amplifier circuit, a wave filter circuit, a signal modulation circuit ahead the acquisition chip, a frequency grasp circuit and the series-wound communication circuit, etc.. The performances of the system were analyzed experimentally. The results indicated that this circuit may achieve the expectation.
