摘要
在外场考核激光烟雾的战术技术性能是烟雾干扰特性试验的最重要手段。为降低生产成本 ,减少试验消耗 ,我们应用基于最小二乘法的多项式拟合技术 ,它能依据少量烟雾弹的直接测试 ,估计众多烟雾弹齐射时的干扰性能。以此为基础 。
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.
