为提高某军用越野车辆在软路面的机动性,提出一种基于滚动阻力实时监测的软路面识别方法。利用软路面测量的特征参数计算出土壤"圆锥指数"(cone index,CI);依据贝克的地面力学"压力-沉陷"公式获得主要由土壤压实阻力构成的车轮滚动阻力系数;通过实时监测车辆和发动机动的运行状态,基于车辆纵向力平衡方程,根据发动机的输出扭矩计算车辆当前行使路面的滚动阻力系数,并与软路面滚动阻力系数临界阈值进行对比...
基于优化包络相关法的罗兰C天波延迟估计算法
罗兰C 天波延迟 包络相关 相关系数
2012/12/25
针对低信噪比条件下,罗兰C天波信号延迟时间估计的准确性和有效性问题,提出了基于优化包络的相关系数时域法。首先,分析了标准罗兰C信号包络的特征,并分别采用微分和二次微分方法对罗兰C信号包络进行优化,形成陡峭的包络信号上升沿。然后,利用相关系数法对接收信号包络和参考信号包络进行匹配,形成的匹配峰值分别对应地波和天波信号到达的时刻,由此可获得天波信号的延迟时间。最后,通过仿真分析和实测信号试验验证,证明...

Periodic geocenter motion measured with SLR in 1993-2006(由SLR观测的地心周期性运动1993-2006)
激光测卫(SLR) 地心运动 地球质量再分布 LAGEOS 1/2
2009/11/18
地球质心(CM)是整个地球的质量中心,地心运动是由地球系统的质量重新分布激励的,特别是流体圈层。利用SLR对LAGEOS 1/2卫星的距离观测,解算了1993-2006期间的地心运动时间序列。然后分布利用小波变化和最小二乘法分析了该序列,发现地心运动存在长期和周期性变化。地心的长期运动表明地壳形状在变化,北半球和180o半球在收缩,南半球和0o半球在膨胀。季节性变化是地心运动的主项,主要是由地球流...
