Fast maneuvering target may lead to the guidance law providing a lower terminal precision. In order to solve this problem, a finite-time sliding-mode guidance law based on Extended-State-Observer(ESO) is proposed. First of all, guidance law design model is established based on two-dimensional relative motion model. Aiming at the design model, combine the theory of finite-time control and sliding-mode variable structure control method to design a finite-time sliding-mode guidance law. Then, a finite-time ESO is designed to estimate target-maneuver and compensate it in designed guidance law. It is theoretically proved that the designed guidance law can guarantee the stability of the system state. Finally, verify the effectiveness of the designed guidance law by means of numerical simulation.
