Research of All-around Digital Receiver Based on Very Low Frequency Remote-Controlled Naval Mine
Guo Da-jiang · Modern Electronics Technique · 2007
Based on analysing sensitivity of receiving system of the naval mine,a new method which can use microcomputer software to accomplish all-around receive underwater of Very Low Frequency(VLF).The theory of digital all-around technology is derived in this article,and it proves that can use software substitute the main part of hardware of the naval mine receiver.And simplifies the sophisticate reception circuit which is two frequency conversions superheterodyne reception circuit and analogue phase demodulation circuit.The capability,reliability and sensitivity of the receiver by this technology are improved greatly.
