Lastly, the best receiving aperture of a laser heterodyne receiver is discussed briefly.
最后简单讨论了激光外差接收机的最佳接收口径。
The super-heterodyne receiver is always applied in modern communication system, mixer becomes the key component as is at the first part of system.
在现代通信系统中，毫米波频段通常采用超外差接收机，混频器作为第一级就成为关键部件。
The results indicate that the effects of atmospheric turbulence on the heterodyne receiver at a horizontal path are significant, but the effects at a slant path are much smaller.
结果表明大气湍流对水平光程上的光学外差接收机的影响很大，而在斜程上湍流的影响要小得多。
