Abstract：In some optical-electronic tracking systems, the sampling frequency of target image is considerably higher than the laser emission frequency of laser range finder. The data transmission amount and the computational burden in this kind of optical-electronic tracking system would be reduced if an event-triggered mechanism has been utilized to control the transmission of measurements. The estimation performance of the system could be guaranteed to stay within the allowable range. In this article, an event-triggered mechanism based on a nonlinear transformation has been designed for the aforementioned system. In order to evaluate the estimation performance of the system mentioned above quantitatively, the recursive formula of Cramér-Rao lower bound (CRLB) for the system with the designed event-triggered mechanism has been proposed. At last, the validity and feasibility of the designed event-triggered mechanism has been verified through simulation under different typical scenarios and experiment under actual air route.
