This paper first discusses the instinct disadvantage of a superheterodynereceiver, 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 superheterodynereceiver.
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.
