As what is concluded from the above that it is practicable to design the digital intermediate frequency receiver with wide band at present 由此可見,在現(xiàn)有條件下實(shí)現(xiàn)寬帶數(shù)字中頻接收機(jī)是可行的。
Finally the fruit of research for my master degree presents in the way of actual de - hopping and digital intermediate frequency receivers that have passed the examination 最終以通過檢測的跳頻解跳與數(shù)字中頻接收機(jī)的實(shí)物作為碩士期間的研究成果呈現(xiàn)。
The de - hopping and digital intermediate frequency receiver can either do the real - time de - hopping processing or be used as a software radio receiver 需要實(shí)現(xiàn)的跳頻解跳與數(shù)字中頻接收機(jī)既能對(duì)跳頻信號(hào)進(jìn)行實(shí)時(shí)解跳,又能做為一臺(tái)軟件無線電接收機(jī)使用。
The thesis that did the research focusing on the realization of real - time de - hopping processing , introduces the hardware and software models of the de - hopping and digital intermediate frequency receiver and describes the key part of the design 本文將對(duì)跳頻信號(hào)的實(shí)時(shí)解跳處理進(jìn)行研究,著重對(duì)跳頻解跳與數(shù)字中頻接收機(jī)的實(shí)現(xiàn)上進(jìn)行論述,并介紹該接收機(jī)的軟硬件模型,對(duì)實(shí)現(xiàn)方案的重要環(huán)節(jié)進(jìn)行闡述。
Then , we introduce the basic structure of pd weather radar signal processing system and their function of each subsystem , mainly including intermediate frequency receiver , clutter elimination , range correcting and smoothness , ambiguity resolution and spectrum estimation 并在此基礎(chǔ)上介紹了氣象雷達(dá)信號(hào)處理系統(tǒng)的基本構(gòu)成與各部分的主要功能,主要包括氣象回波中頻接收、雜波抑制、距離訂正、平滑處理、解模糊和譜矩估計(jì)等。
