机动目标的机动不确定。机动频率我..
在机动目标跟踪中，机动目标模型是机动目标跟踪的基本要素之一，一般希望机动目标模型能准确表征目标机动时的各种运动状态。比较常用的模型有匀速运动(CV)模型、匀加速运动(CA) 模型、时间相关模型（Singer）和机动目标“当前”统计模型。上述模型均采用机动频率表征目标的机动情况。在应用当中，通常采用固定的机动频率，这就表示机动目标的机动时间是一定的，而实际上机动目标的机动时间是不断变化的，也就是说机动频率是不断变化的，采用固定机动频率必然会带来误差。采样周期在0.5―2S时，机动频率越小跟踪精度越高[1]，但机动频率仍然是固定值。本文提出的基于神经网络的机动频率自适应调整方法可以使机动频率随机动而变化，从而提高状态估计的准确性，提高跟踪精度。本文将小波神经网络用于机动目标跟踪中机动频率的自适应调整，该算法对机动目标“当前”统计模型中的机动频率进行实时修改, 从而自适应的改变机动频率,使跟踪算法与目标的真实状态更接近。该算法采用小波神经网络的离线训练，实时性好。-The maneuver of the maneuvering target is uncertain. The maneuvering frequency is constantly changeable, but traditionally it is beforehand determined as a constant based on the target state estimation in the state model of the maneuvering target. The maneuver of the maneuvering target makes the kinematics equation of the target model mismatch with the practical motion model and the tracking error will be increased. Based on the advantages of the self-learning, the rapid convergence rate and the nonlinear approximation ability of the wavelet neural network,

ZD-BS是一个基于asp+access的个人blog系统
程序特点:
1.数据结构合理，执行效率高
2.缓存优化，在资源和效率上充分考虑平衡
3.可定制能力强，并不是傻瓜式系统，如果需要，用户应当修改源码(参考下面使用说明)
4.开源，免费
用户admin密码admin
编辑注：这个版本是无数据库的，所以只能升级不能重新安装，(为方便新使用朋友在data目录下的数据库为1.2的可以正常使用.)只需要把原来zd-bs的数据库复制进去就可以了，链接参数等请修改config.asp。在IE6下后台的表格可能会出现width100％的bug-ZD-BS is based on asp+ Access personal blog system program characteristics: 1. A reasonable data structure to implement high efficiency 2. Cache optimization, efficiency in terms of resources and take full account of the balance 3. Customizable ability, not a fool system, if required, the user should modify source code (refer to the following instructions) 4. open source, free user admin password admin edit note: this version is no database, we can only upgrade can not be re-installed, (For the convenience of the new use friends in the data directory of the database for normal use can be 1.2.) only to the original database zd-bs copy into it, modify the link parameters config.asp.
