How to estimate the Performances of Laser-attenuating smoke Screen in the light of a few samples

It is necessary to test the disturbance capability of smoke screen attenuating Laser in field. In order to reduce experiment consumption and production cost, we introduce an estimation method based on a few samples. According to the outcome of actually measuring several sampled smoke bombs, using polynomial approximation by Least Square, we can estimate the disturbance capability of many smoke bombs together. It has been proved in practice that when we test the decay characteristic of the smoke curtain to laser, we can achieve satisfactory accuracy by using only polynomial approximation of 4th degree; it is also adaptable in laboratory test.
