Line-of-Sight of Reflectors Reconstruction and Stabilization Technique based on Fastest Differential Tracker

Abstract

Abstract In order to overcome the shortcomings of half-angle reflectors mechanism stabilization configuration, we study the Line-of-Sight (LOS) of reflectors reconstruction and stabilization technique. A LOS reconstruction and stabilization configuration of reflectors is designed and modeled. Firstly, we design the Fastest Differential Tracker (FDT) to estimate relative angular rates, then propose a two-coordinate modeling method that is easy to analyse disturbance isolation performance, thirdly we study the control system isolation deegree to the measurement noise and carrier disturbance. The simulations indicate that FDT has superior performance in tracking speed, noise suppression and steady state vibration suppression, and that the stabilization accuracy, in consideration of both noise and carrier disturbance, is about 70μrad(1σ). The experimental results show that reflector platform stabilization accuracy based on LOS reconstruction configuration is about 80μrad(1σ).
