AN ALGORITHM OF DETERMINING LINE OF SIGHT COORDINATES OF OBSERVATORY AND TURRET IN IMPROVED ZSU-23-4 SELF-PROPELLED ANTI-AIRCRAFT GUN
Keywords:ZSU-23-4; Vehicle’s attitude; Euler angles; LOS angles; Stabilized angles.
In the improved ZSU-23-4 self-propelled anti-aircraft gun, the observatory is attached to the turret and the turret is mounted on a base vehicle as a carrier vehicle. The line of sight (LOS) coordinates of the observatory and turret are automatically determined based on the rotary angles and the vehicle’s attitude. The simulation of the LOS angular coordinates and angular rates are conducted in MATLAB. The results show that the characteristics of angular coordinates and angular rates are smooth enough, ensure stability for the tracking control system.
