摘要
设计并实现了光波非触发主动引信传感信号光波接收系统,通过对低信噪比下的传感信号进行放大、滤波、检波、自动增益控制等调理,分析引信光波的原理和参数设置,采用双运放LM358设计光波,测试结果表明,当输入传感信号的起控点在0.1 mV,有效信号范围为0-5 mV,放大环节,实测放大倍数为44300倍;带通滤波环节,实测通频带为87一2215 Hz;AGC环节,起控点在0.1 mV,动态范围为34 dB.测试性能稳定,达到设计要求,可以有效应用到非触发引信光波工程实践中.
The paper designs and implements the waves are not trigger fuze sensing signal receiving system actively,through the sensor under low SNR signal amplifying, filtering, detection, automatic gain control and so on, analyzing theprinciple of fuze receiver and parameter setting, with double op-amp LM358 receiver design, test results show that whenthe input signal receiver of the locus of control in 0.1 mV, effective signal range of 0 - 5 mV, amplification, the measuredmagnification of 44300 times; Band-pass filter, the measured passband is 87-2215 hz; AGC link, the locus of control in0.1 mV, dynamic range is 34 db. Test performance stability, meet the design requirements, can be effectively applied.
