Accuracy of light target coordinate determination by dissectoral tracking system with regard to nonstationary state of noise

摘要

Abstract: The accuracy of minor dimensional light target coordinate determination by a dissectoral tracking system with regard to the non-stationary state of noise is analyzed. The results are obtained by statistical simulation of the extended Kalman filter with a computer. Comparison of the suggested signal models is conducted. The robustness and stability of the algorithm to deviation of the model parameters from nominal value and the accuracy of coordinate determination at different target contrast, at the relationship signaloise and dissectoral tracking system parameters, have been examined. !3
