| Abstract: | 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. |
