According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.
结合武装直升机在巡航或搜索地面目标的特点,给出直升机航迹模型为协方差平稳随机模型,在线估计有色噪声参数,对测量噪声去相关,对直升机航迹进行卡尔曼滤波与预估,最后对有色噪声条件下的航迹进行了仿真研究;在数据非常有限的情况下,准确地预测又很困难,本文提出了用灰色系统理论解决直升机航迹预测问题,建立了灰色系统GM预测模型和n次累加残差模型并对GM预测模型进行修正,在每个采样期间内,实时在线建立GM预测模型和残差模型以提高预测精度。

The paper founds GM(1, 1) model of gray prediction theory in order to predict level displacement,and forecast horizontal displacement of 8-8 section of the Olympic Games project with it and compares forecast data and actual data.The result is that GM(1, 1) model may forecast short-term horizontal displacement after the model is proved eligibility. In order to manage long-term horizontal displacement,the paper founds metabolism GM(1, 1) model.At first, founding GM(1,1) model with known data and forecast next numerical value,next renewing founded GM(1,1) model with numerical value at the same time abnegating first data,and then forecast nest numerical value with same method.
本文为了预测土钉支护水平位移,建立了GM(1,1)灰色系统理论预测模型,应用灰色预测法GM(1,1)模型对奥运工程地下通道I标段8-8剖面的土钉支护产生的水平位移进行了预测,并与实测值进行比较,得出灰色预测法模型经检验合格后可以对工程进行水平位移的短期预测;为了使GM(1,1)模型同样适用于长期预测,用新陈代谢的GM(1,1)模型,即根据己知数列来建立GM(1,1)模型,预测一个灰数值,然后不断地将预测值补充到己知数列之后,每补充一个再去掉一个最老的数据构成新的数列,建立一个新的GM(1,1)模型,预测下一个值。

Methods Fifty F-344 rats were divided into four groups, GM only、PAA+GM、PAA only and saline control. ABR thresholds at different frequencies were measured at different times and hair cell losses were numerated. Two-dimensional diffusion assays in the culture medium were performed to evaluate the effect of PAA on the antimicrobial activity.
选用健康F-344大鼠50只,随机分4组:Ⅰ为GM、Ⅱ为PAA+GM、Ⅲ为PAA、Ⅳ为生理盐水对照组;通过观测4组大鼠不同时期、不同频率听性脑干反应(auditory brainstem respons,ABR)阈值的改变;计数耳蜗毛细胞死亡率,以观察PAA对F-344大鼠GM耳蜗毒性的拮抗作用;用双向扩散血清培养基检测法观察PAA 对 GM 抗菌活性的影响。
