frequency rate meaning in Chinese
频率
Examples
- Experienced a construction site accident frequency rate of 0 . 68 per 100 , 000 manhours in comparison to the hk construction industry rate of 1 . 89 per 100 , 000 manhours
2003年非致命意外率为每十万工时0 . 68宗，远低于本港建造业每十万工时1 . 89宗意外的比率 - Data that focus not on age but on length of service give similar results and confirm that the frequency rate of work accidents decreases with length of service
事故的次数的多少与人的年龄无直接关系，但与服务的年限的长短有关，事故的频率随著服务年限的增长而减少。 - The theory of soplat using frequency rate is discussed in chapter 2 . based on this theory , this chapter studies the observed discrete - time signal . the crlb of continuous wave and coherent pulses frequency estimation are also studied
论文第二章讨论了利用频率变化率的单站无源定位原理,在此基础上,介绍了单站无源系统中接收信号的模型,并分析基于各模型的频率估计的cramer - rao下界。 - The radar which is embedded on platform sidelooking , but the platform will be disturbed by airflow inevitably . so , the radar will have a small sloping angle , thereby , the doppler centroid that is not zero and doppler frequency rate need to be estimated from the raw echo data in order to focus in azimuth commendably
场景成像的合成孔径雷达一般是正侧视放置,但是载机不可避免的要受到各种扰动影响,雷达会有一定的斜视角,从而导致了多普勒中心频率不为零,多普勒调频斜率也随着雷达斜视角改变。 - Quite a few of new methods of soplat have been proposed in the last decade , most of these methods add new measurements values to the bearing - only method base on the particle kinematics . this paper studies the challenge technology of soplat method using frequency rate , including frequency and frequency rate estimation
近几年来,这一技术得到了新的发展,质点运动学原理和多年的研究证明,在传统的只测向方法的基础上增加多普勒频率变化率的算法可提高无源定位系统的可观测性,实现瞬时定位,但同时也对信号接收机提出了更高的要求。
