干擾和噪聲對激光制導性能及精度的影響
[Abstract]:In view of the large error of the line-of-sight angular velocity of a laser seeker, it is pointed out that the noise of the line-of-sight angular velocity is generated by the mutual action of the noise, the disturbance and the friction of the detector in the angular tracking loop. The stable tracking loop model of the seeker is established according to the control principle of the seeker, and the influence of these error factors on the stability and tracking performance of the seeker and the output command of the line-of-sight angular velocity of the seeker is quantitatively analyzed. Then, the noise characteristic of the line-of-sight angular velocity of the output of the laser seeker is measured, and the function relation with the target distance is established and the simulation is carried out in a guided weapon guidance model. The results show that the change of the angle of the body roll attitude is great, and the change of the rudder angle is also large, and the influence of the angular velocity command noise on the total trajectory and the target amount is small at the close range, which is in good agreement with the actual detection result. However, when the angular velocity command is at the noise peak in the near-close time, it is too late to correct the influence on the near-range attack area of the missile, and the research methods and conclusions have a certain reference value to the actual research and test of the seeker and the tactical use of the missile.
