Design principle and strategy of radar maintenance simulator

Unlike operation simulators, radar maintenance simulators focus more on the simulation of specific signals, circuits, and fault logic, which has problems such as multiple simulation signals, complex structures, and high costs. This paper analyzes the requirements for radar maintenance teaching and training, proposes general principles for designing radar maintenance simulators, summarizes the design characteristics and difficulties of maintenance simulators, and designs a maintenance simulators based on multi-channel signal acquisition and playback technology, which can improve the effectiveness of maintenance simulation training while significantly reducing development costs.
