With the assumption of coordinated turn maneuver,a generic approach for target tracking CRLB calculation was investigated under the conditions of active and passive measurement,and the essential reason for possible CRLB s sudden increase caused by maneuver was also analyzed from the perspective of matrix theory,wh. 以转弯机动为例,研究了有源(主动)和无源(被动)两种观测条件下目标跟踪CRLB计算的一般方法,并通过矩阵理论分析了目标机动可能引起的CRLB突变的原因,为机动目标跟踪的算法性能评估提供了有效手段。 2. Aiming at the target motion uncertainty when target has a coordinated turn maneuver,a state estimation algorithm based on expectation maximization(EM) algorithm was derived. 针对目标做转弯机动时产生的运动模式的不确定性问题,提出了基于期望极大化(EM)算法的转弯机动目标跟踪算法,采用转弯速率来描述目标的转弯机动,并将转弯速率作为待估量,用EM算法对转弯速率序列进行估计,从而获得对目标状态的精确估计。 4)  extreme turn 急转弯 1. In recent years,underground structures become more crowded in urban area,for reducing the interference with existing ground or underground structures,the construction cases of shield tunneling in extreme turn sections have an increasing tendency day by day. 近年来,随着都市地下结构物的密集化,为减少与现存地面或地下结构物间之干扰等因素,潜盾隧道急转弯段的施工案例有日渐增加之趋势。 5)  sharpest turn 最急转弯 6)  a hairpin turn [curve] U 形急转弯 补充资料：慌慌急急 1.见"慌慌促促"。 说明：补充资料仅用于学习参考，请勿用于其它任何用途。 参考词条 ©2011 dictall.com
