On the basis of the transmission line theory, combined with the characteristics of 1553B bus and its structures, distribution parameters of the equivalent differential circuit, the damage was deduced uniformly arbitrary input output response of the 1553B bus, propagation constant matrix, characteristic impedance matrix and transfer function matrix, established the mathematical model of cable frequency domain after cleverly simplified model, and with the test data in matlab by means of parameter identification, to estimate the parameters of cable, eventually have to close to the real value of nondestructive line mathematical models, and to the related parameters to build simulation model to do simulation experiment, the experimental results show the correctness of the mathematical model, It provides reference for the research of 1553B bus.
