| Abstract: | The requirement of optical signal detection from nuclear explosion in space is proposed. Based the analysis of source, a cirruit with a band pass filter from 1Hz to 4000Hz and measures to anti-jamming, is designed for optical signal detection. The sensitivity, SNR, frequency and linear range method of reducing errors with software is of circuit are verified by experiments. The given. |
