Influence of radar guidance system noise on precision of guidance and control

Based on adjoint method, the adjoint model of the original system was obtained, and then the non-dimensional system was deduced using the time scale transform method and the transfer function method. It is concluded that angle noise and target glint play an important role in the precision of radar guidance and control system, moreover, the induced miss distance does not decrease to zero with the increasing flight time of the engagement. Researching on the ratio of the miss rms to the glint rms show that the precision of guidance and control is closely related to the glint frequency. These results have a great significance in the primary design of project.
