Abstract: In order to simulate the target echo energy of semi-active laser guidance in actual combat environment, an injection laser energy simulation device was designed and developed. The laser-guided energy transfer process and simulation techniques were researched. First of all, aiming at the working process of laser-guided weapons, the laser scattering and attenuation model in the atmosphere were established. Fog, rainfall, and interference smoke existing in actual combat were modeled and simulated. Then, the overall scheme of the laser target echo energy simulator was proposed. The DPS-A laser and Brewster angle polarizer were used to simulate the laser attenuation. A fiber coupling and uniform light collimation system was designed. Finally, a laser-guided semi-physical simulation system was constructed, laser echo energy simulation experiments, seeker calibration and laser terminal guidance experiments were performed, respectively. The results show that laser energy simulation error is less than 3%, the residual error within the linear range of the seeker is less than 0.08°, the accuracy of angle measurement is less than 0.45 mrad, and the tracking error of line-of-sight angle in the terminal guidance process is less than 0.2°. The system can simulate laser energy transmission in a variety of real-world environments with high accuracy, which can meet the requirements of laser-guided semi-physical simulation. -
