The hardware-in-the-loop simulation is widely used in laser semi-active guidance weapon experiments,the authenticity of the laser signal is the key problem in the simulation system.Due to the limitations of the simulation devices, the energy distribution of the jamming laser was uneven.In order to assess the impact of the optical homogeneity,combining the application of simulation,the far-field energy distribution was measured.By optical simulation and actual test,according the receiving optical system entrance pupil,the effect on the beam quality to the simulation result was analyzed. By comparing the different working state between actual condition and hardware-in-the-loop simulation,the output of laser seeker and laser guided weapon trajectory were obtained, the influence of the uneven signal was analyzed.In conclusion it was pointed out that the difference between simulation system and actual system has little influnece on laser jamming. The research is helpful to design and evaluation of laser guided weapon simulation. |
