That’s a heterodyne receiver.

那是外差式接。

The radio receiver cut out.

无线电接突然停了。

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，该接本地模板信号为非限定M个接脉冲波形平均。

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.

卫星角反射器作为激光测距统中合作目标, 其主要作用在于提高地面接围内反射光束能量密度。

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.

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