That’s a heterodyne receiver.

那是外差式接收机。

The radio receiver cut out.

接收机突然停了。

Generalized UWB-ATR receiver is proposed, in which the local template waveform is computed as the average of the channel responses to nonfinite M transmitted reference pulses.

摘要提出了一种广义UWB-ATR接收机，该接收机的本地模板信号为非限定的M个接收的参考冲波形的平均。

Satellite retroreflector is used as laser ranging cooperative target to improve the intensity of reflected beam, which has close relationship with processing parameters of the retroreflector.

卫星角射器作为激光测距系统中的合作目标, 其主要作用在于提高地面接收机范射光束的能量密度。

Considering the issue of the complexity, which means to use separate TF-domain re-ceiver, we prefer adopting VSL access scheme whether increasing spreading code as-signment on T-domain or F-domain.

若因考量硬体复杂度而采用分离时频率接收机，则使用可变展码长度存取技术将是较佳的方法。
