Effect of smoke screen interference on the dimension of the laser spot

The effect of smoke screen interference on by the dimension of laser spot on the surface of the target is studied. To enhance the anti-jamming ability of the laser weapon, the relationship among the dimension of the laser spot, the received laser power of the detector from the target, and interference effect is obtained before discharging the smoke screen and after that through deduction and calculation of relative theory. By this way, the interference effect of smoke screen is simulated. At last, the conclusion is proved by experiment. It is found that if the dimension of laser spot is smaller, the power is more focused, the interference effect is worse, and the anti-jamming ability is betterr.
