Radio Fuse Including In-kind Digital Simulation Key Technology Research

In this paper we discussed the digital simulation system of radio fuze with real object, mainly introduced the process of designing the software part of this system -simulation software.The digital simulation system of radio fuze with real object use the signals obtained beforehand to simulate a free space similar to the real space in the coaxial-line testing device. Then it collect the signal produced from the fuze(with power supply) which was placed in the coaxial-line testing device . By the signal we can analyze the fuze's working information and judge if the fuze worked normally.In this paper we systematically introduced the process of simulation software by the theory of software engineering and resolved the synchronous problem of executing the D/A and A/D conversion simultaneously.In addition, we presented two schemes and its detailed implementations in two different application environment in this paper. We also introduced all kinds of input signals the simulation system needed and the way to obtain them. The emphasis is standard target testing signal and the special data collection system which was designed to collect the signal.
