【Abstract】 To implement accurate and real-time simulation of signals of some missile under various target environments, the technique of in-system programmable (ISP) is applied to realize a variety of signals such as frequency controllable pulses, sine signal and noise, etc. And besides, the simulation circuits can receive asynchronous data and be under the control of it. The paper introduces generation principles of the signals and design methods of the simulation circuits. Some circuits and simulated waves are given as well. As a result, the simulation circuits are reduced and the simulation precision is increased using ISP technique. Meanwhile, by using different methods to describe data relations and signals relations, the design process is simplified and architecture of the circuits is clearer.更多还原
