Research on Relation between Sampling Pulse Width and Output Signal Amplitude for Ultra-wideband Radio Fuze

doi:10.3969/j.issn.1000-1093.2016.11.004

Abstract

Abstract: Ultra-wide bandwidth (UWB) radio fuze receiver receives a target echo signal based on a correlation receiving principle. The signals from fuze receiver are obtained by the correlation calculation of echo signal and delayed sampling pulse signal. The sampling pulse width can be optimized to increase the detection sensitivity of UWB fuze. A correlation receiving mathematical model of UWB fuze is established based on the correlation receiving theory, and the relationship between the sampling pulse width and the amplitude correlation receiver function is analyzed. The received output signals are simulated when transmitted pulse width is 50 ps, 100 ps and 200 ps. The simulated results show that the fuze-received output signal has the maximum amplitude when the sampling pulse width is the same as the transmitted pulse width.

Key words: ordnance science and technology, fuze, ultra-wide bandwidth, correlation receiving, time-domain Doppler
