【摘要】

：

发射阵地上空扰动引力对弹道导弹主动段飞行影响很大.通过使用基于SRTM数据的地形分类,计算了七种地形类别的纬向、经向和径向扰动引力,并对弹道扰动引力进行了分析和比较.经过计算,在近地表各地形扰动引力三分量均与平原相差很大;而弹道高度大于25km时,扰动引力偏差逐步收敛甚至趋向于0.这表明扰动引力对导弹低空主动段影响很大,高空高速飞行时影响不大,发射点位于我国多山或青藏高原地区,扰动引力对导弹落点影

一种基于自适应权值调整的载波跟踪环方法

在室内环境中,接收机接收信号衰减严重甚至出现频率阶跃的情况,传统接收机跟踪环路无法稳定跟踪,从而影响接收机的最终定位精度.针对上述问题,本文提出了一种基于自适应权值调整的载波跟踪方法.根据动态门限,自适应地调整鉴频值和鉴相值的权值,将调整后的鉴频值和鉴相值作为观测误差矢量,采用卡尔曼滤波器替代传统的载波环路滤波器,建立新型的二阶锁频环辅助三阶锁相环的载波跟踪环模型.仿真结果表明,在弱信号环境下,该

卫星导航接收机的同步块信号调整解调方法研究

研究了一种新的卫星导航接收机导航电文解调算法——BASS(同步块信号调整)方法.通过分析卫星导航信号有用DFT分量的相角获得载波的精细频率和与导航电文信息,在方法实现的过程中考虑了核函数相角不连续的原因并作了补偿,最后用仿真和实际信号分别对该方法进行验证并与传统锁相环方法比较,结果表明:BASS算法捕获频率精度可达10HZ,能有效输出导航电文信息.
