【Abstract】 In order to overcome the shortcomings of traditional computational order analysis, such as low resolution and unable to distinguish dense order and cross order, the Vold-Kalman filter order analysis theory is introduced. And through the virtual instrument technology to achieve the above theory, a set of order analysis system is designed and developed. Simulation experiments and practical applications shows that the method can effectively solve the problem of frequency-ambiguity. Compared with the traditional calculation order analysis, the resolution of the order spectrum can be greatly improved, and the system operation is quick and convenient, and the analysis result is accurate and reliable.更多还原
