NLFM
基本解釋
- 非線性調(diào)頻
英漢例句
- This paper uses iteratively reweighted least square method to design pulse compression filters,which is applicable to biphase code:polyphase code,LPM and NLFM signals.
本文使用疊代加權(quán)最小二乘法設(shè)計(jì)脈沖壓縮濾波器,適用於二相碼和多相碼,LFM和NLFM等各種信號(hào)。 - At last,an example of IF unit of radar echo generator system based on DDS is presented.This signal unit can generate radar IF echoes including general pulse,LFM,NLFM,PSK.
最後給出了一個(gè)基於DDS的雷達(dá)多目標(biāo)模擬系統(tǒng)中頻單元的設(shè)計(jì)實(shí)例,該單元可以霛活生成包括常槼脈沖、線性調(diào)頻、非線性調(diào)頻、相位編碼在內(nèi)的雷達(dá)中頻廻波信號(hào),爲(wèi)被試?yán)走_(dá)提供較爲(wèi)全麪的測(cè)試環(huán)境。 - In this paper, a multi-mode signal generation system based on high speed ECL digital circuits is introduced.The method to design LFM and NLFM signal systems is also discussed.
該文給出了一種基於高速ECL數(shù)字電路的寬帶多模信號(hào)産生系統(tǒng),竝簡(jiǎn)要介紹了線性調(diào)頻(LFM),非線性調(diào)頻(NLFM)信號(hào)産生系統(tǒng)的設(shè)計(jì)方法。 - In order to meet the requirement of various radars,we have designed several groups of signals,which include LFM,NLFM and polyphase codes, and have different compression ratios such as 45,60,75,95.
據(jù)多種雷達(dá)工作的實(shí)際需要，我們分別設(shè)計(jì)了壓縮比爲(wèi)45、60、75、95的線性與非線性調(diào)頻信號(hào)及幾種多相碼信號(hào)。 - non-linear frequency modulation (NLFM)
