| Target State Estimater(TSE) is an important and indispensable part of Integrated Flight and Fire Control System (IFFCS) . This article takes the ground mobile object as the study model. It established the system state equation and observation equation from the perspective of promoting system accuracy, simplifying the calculation and facilitating the engineering realization, the TSE was set up by using the Kalman filtering calculation method in the wake of linearizing the observation equation to make it adapt the precondition. After that Monte Carlo simulation method was used to evaluate performance of the TSE. It means the system state filtering and one step predicting values are available through using filtering calculation to process the analog measure values produced by adding the white noise upon the real values of the mobile object to evaluate the TSE performance. The results illustrate the designed TSE meets the specification requirements. Finally put the TSE into the IFFCS and used Matlab5.3 to conduct a digital simulation on the whole closed-loop for the purpose of testing the TSE' performance in and influences on the IFFCS, the output curves show the TSE also works pretty well and cuts the mustard. |
