Method of network cooperative targeting for helicopter electro-optical system

Aiming at the detection requirements of helicopter networking and informatization, a method of using data link information to quickly guide the airborne electro-optical system realizing target aiming was proposed. The indication errors during the guidance process of network information were analyzed. The coordinate transformation method and delay processing algorithm of target information, and the aiming line deviation estimation method of electro-optical system were given. Finally, the effects of data accuracy, data rate, delay time on network cooperative target aiming for helicopter electro-optical system were studied by simulation experiment. The simulation results show that reducing the data latency, improving the data rate and data accuracy are the effective approaches of reducing the aiming error of network cooperative target. In addition, it can improve the estimation accuracy of target state and reduce the estimation errors of target aiming line by using the reasonable target information delay processing algorithm.
