有源方式 meaning in English

active mode

The auxiliary signal is injected into antennas from the ports of antennas in the first calibration project for channels uncertainty . this thesis studies the least squares ( ls ) algorithm , the subspace - based algorithm and the correlation algorithm based on the mentioned project
通过理论研究，确定基于有源方式的两种天q线阵列校正方案：一种是从天线馈电口注入辅助信号，另一种是从空中注入辅助信号。
3 . passive and active time - domain demodulation schemes were demonstrated based on a fiber bragg grating used as a tunable filter controlled by a piezoelectric stack , which was driven by an electrical sine wave signal . the measured strain applied on the sensor axially could be judged by observing the interval of the output between notches within a driving period in time - domain
利用匹配滤波技术，分别采用无源和有源方式，借助受pzt驱动的解调光栅，将待测应变信息变为时序负脉冲间隔的变化，利用常规的示波器观测同一扫描周期中两负脉冲在时域中间隔的变化来确定待测应变的变化。
