Abstract: The testing system for creeping movement attitude of soldiers was designed for overcoming the low efficiency and strong subjectivity existing in the training appraisal with the traditional method. The real-time detection for the creeping movement attitude of soldiers can be implemented by the testing system based on infrared and single-chip computer technologies. The parallel multiplexing signal processing circuit and beam path adjustment setup were designed to direct at the characteristic of great IR interference in the open air, which improved the anti-interference ability and acceptance range of the system. The synchronous simulation of sound in battlefield enhances the efficiency of training. The training effect evaluation provided by this system can meet the requirement of the training.
