A Study on Information Transmission Properties of Exterior Trajectory Acceleration Storage Measurement System

针对外弹道加速度存储测试系统正确传输被测信息以及外界干扰对系统影响的问题,研究并计算了被测信息的时间熵、存储测试系统信道容量、系统抗干扰容限等参数及其相关关系.理论计算和实验结果表明,存储测试系统的信道容量大于被测信息的时间熵,存储测试系统能正确传输被测信号,同时给出了系统正常工作时所能承受的最大外界干扰.

Aiming at the problem on the acceleration storage measurement system of exterior trajectory accurately transmitting information measured and the effect of environment interfered on the system, several important parameters such as the time-entropy of the information measured, the channel capacity of storage measurement system, anti-interfering tolerance of the system, were calculated. The correlativity was further investigated. The theoretical and experimental results show that the channel capacity of storage measurement system is larger than time-entropy of information measured, and the storage measurement system can accurately transmit the measured signal. The most environment interfered that the system can endure was given at normal work.
