relative acceleration meaning in English

相对加速度
相对加速仪

To avoid collision with static and dynamic obstacles , the magnitude and direction of the acceleration of mobile robot was adjusted dynamically in real time based on the relative acceleration information
相对坐标系中，采用包含相对加速度信息的避碰算法，通过动态实时地调整机器人加速度的大小和方向，使其避开障碍物。
In this paper , the concept of acceleration ambiguity function ( aaf ) and acceleration resolution is put forward for the first time . using aaf , the effects of target ' s relative acceleration on several outputs of a linear - phase matched filter are analyzed , such as the output signal - noise - ratio loss , the doppler resolution , the constraint on optimal accumulative time ( opt ) and their tolerable limits
论文首次提出并研究了加速度模糊函数和加速度分辨力的有关概念，并以加速度模糊函数为分析工具，详细讨论了加速度对线性相位匹配滤波器的输出信噪比的损失程度、对多卜勒频率分辨能力的影响程度、对最优相参积累时间的约束关系以及线性相位匹配滤波器输出受加速度影响的容限等问题。
