線性階層頻率調變(Linear Step Frequency Modualtion ,LSFM),屬於Chirp
Communication 的一種,擁有線性調變脈衝的特性,很適合無限的通訊環
境,常被用於軍方雷達使用上。Chirp 如果以聲音設備撥放,聽起來會像是
鳥兒鳴叫,因此得名。起先,這樣的訊號是在1994年,由Homann 教授為
了雷達應用而設計出來,後來到了1947年, 由IEEE 院士Sidney Darlington
更進一步發展,將其改良為現在熟知的樣子,脈衝壓縮雷達。
近年來,物聯網的議題越來越受到重視,因此低功號的通訊也因此崛
起。而線性階層頻率調變,即擁有低功號、對督普勒效應免疫...等特性。
本論文會先以軟體模擬線性階層頻率調變,設計出一套規格後,將線
性階層頻率調變以硬體實現,與硬體的化簡,並評估其複雜度。最後將自
製軟體定義無線電線平台,結合硬體,將線性頻階層率調變
(LSFM)發射至空中,並以此平台去接收,觀察線性階層頻率調(LSFM)變在
不同的距離、環境會有那些不同的反應。
Wtih Communication Technology improvement, a new conept of Radio has
borned, Software Dene Radio.Typically Radio comminication System were imple-
mented by analog circuit, inorder to adjust variance communication syatem, SDR
replace some Baseband module with digital circuit. It support user a platform which
can realize dierent communication system with a general platform. In this paper,
I will implement Linear Step Frquency(LSFM) , which is a kind of radar technology
that have pulse compression characteristic, in SDR platfom.By doing some experi-
ment, realize the signal in variance enviroment performance.
