Bank-to-Turn Optimal Guidance with Linear-Exponential-Gaussian Performance Index and Constant Acceleration Bias

In this paper, the optimal guidance law of a Bank-To-Turn(BTT) missile derived by the Linear-Exponential-Gaussian (LEG) performance index and with constant acceleration bias is proposed. The optimal control gain can take both system and measurement noises covariances into consideration. Therefore, the miss distance and rolling execusion can be reduced in the heavy measurement noise environment.
