superheterodyne receiver /ˌsuːpəˈhɛtərəˌdaɪn/
-
1.
N a radio receiver that combines two radio-frequency signals by heterodyne action, to produce a signal above the audible frequency limit. This signal is amplified and demodulated to give the desired audio-frequency signal 超外差式收音机 (Sometimes shortened to superhet)

-
This paper first discusses the instinct disadvantage of a superheterodyne receiver, which is that it has more spurious response.
本文首先指出了超外差接收机的固有缺点，即它有更多的虚假响应。
-
Finally, it points out that, as far as wide open receiver is concerned, to suppress or reduce the spurious response is one of the most important tasks in designing a superheterodyne receiver.
最后指出对于宽开接收机而言，抑制或减少虚假响应是设计超外差接收机的重要任务之一。
-
The system uses the emitter to send ultra high frequency signals after coding with signal coder and the secondary superheterodyne mixing receiver to accept the moving target signals.
