Especially when the power of green laser pointer is high enough

Regardless of hit the point at which the target have the same kill probability, hit a different face of the parallelepiped, killing probability of the target. Equivalent of wearing body size, location, and each face should kill probability and other parameters by the target size, the power of vulnerability and attack weapons warhead. Equivalent to the vulnerability of the body of the introduction of weapons shooting range performance computing and specific objectives, fuze, warhead to isolate, to simplify the difficulty of the weapons range performance simulation. Evaluation of Operational Effectiveness of the mathematical model of this paper are calculated by the Monte Carlo method simulation kill probability of the laser-guided bombs. During the simulation, the laser-guided bombs to hit the equivalent vulnerability of the body surface. Especially when the power of  green laser pointer is high enough.
Uniformly distributed random number sampling to simulate the laser-guided bombs on the target whether destruction. Random wind interference cloud on the accuracy of the mathematical expectation of the random wind is 0, the random wind variance as the parameter changes from 0-1.0. 28 of 34 Graduation Project (Thesis) random wind of the existence of the special paper introduces a weather vane principle error of the laser-guided bombs. From Table 3, we can see, with the random mean square deviation of the wind increases, the CEP of the laser-guided bombs and hit the error variance increases, indicating that random wind to increase the spread of the laser-guided bombs. Speed tracking method used because of the weather vane laser-guided bomb guidance law for random wind a great influence on the accuracy of the laser-guided bombs. The suitable and professional commission method of  green laser pointer  is utilized.
A proportional guidance law, affected by the wind is relatively small. Interference cloud hit accuracy interfere with cloud height and visual distance as a parameter to change the remaining parameters as shown in Table 4. If the laser-guided bomb seeker in a laser pulse period. Received laser pulse signal, arrived after the laser pulse signal to generate a control signal. Better than target reflected laser signal interference cloud located above the target, the interference of cloud reflection to reach the laser-guided bomb seeker, such a laser seeker will be able to effectively eliminate the interference cloud reflected laser signal. Interference cloud of laser-guided bombs is to reduce the maximum and minimum range of the laser-guided bomb seeker. The personnel will do the testing and commissioning process of the power of green laser pointer .
Can be seen from Table 4, when the interference cloud highly little or visual distance is large, the CEP of the laser-guided bombs and hit the error of mathematical expectation, variance reduced compared to the interference-free cloud. This is due to the error does not interfere with cloud reduces the maximum range of the laser-guided bombs seeker, but contains the machine to put the laser bombs, from the control range (maximum range of the laser-guided bombs) is greater than 1km laser bombs have enough time to correct the error. Interference cloud also reduces the loss of control of the laser-guided bomb seeker distance (minimum distance of the laser-guided bombs), "get off the recent bomb" 29 34 Graduation Project (Thesis) special paper error decreases , shooting accuracy.  green laser pointer  has the very fabulous appearance.
Visual interference cloud distance of 0.1km, interference cloud height is greater than 145m from the control distance of the laser-guided bomb is reduced to 600 - 700m, laser bombs, there is no time to correct the error, the error of laser-guided bombs hit a sharp increase big. From the above analysis shows that the presence of interference cloud so that the laser-guided bombs from the control time delay. If larger put in error, there is no enough time for amendments, it is difficult to accurately hit the target. Visible interference cloud the size of the laser bomb attack area. Carrier aircraft attack directions affecting the laser-guided bombs on the target kill probability of kill probability is not only related with their hit accuracy is also related to the target vulnerability. It is our   green laser pointer has been used in many applications and industries.
