　　英國倫敦大學(xué)學(xué)院（University College London）的Hugh Griffiths教授應(yīng)邀于2013年4月12日至16日對(duì)我校信息與電子學(xué)院進(jìn)行訪問，并于13日在北京理工大學(xué)4號(hào)教學(xué)樓233會(huì)議室開展了學(xué)術(shù)交流活動(dòng)，做了主題為“The Challenge of Waveform Diversity”的學(xué)術(shù)報(bào)告。報(bào)告會(huì)由信息與電子學(xué)院院長龍騰教授主持，出席報(bào)告會(huì)的有毛二可院士及信息與電子學(xué)院部分教師、學(xué)生共30余人。

　　Hugh Griffiths教授在學(xué)術(shù)報(bào)告中詳細(xì)講述了英國雷達(dá)的研究起源、雷達(dá)波形模糊函數(shù)、超低副瓣波形設(shè)計(jì)、自適應(yīng)波形多樣性的應(yīng)用與挑戰(zhàn)、認(rèn)知雷達(dá)的研究現(xiàn)狀等。Hugh Griffiths教授對(duì)蝙蝠信號(hào)有非常深入的研究，報(bào)告以大量的蝙蝠信號(hào)頻譜圖和真實(shí)的蝙蝠信號(hào)聲音生動(dòng)地展示了蝙蝠在執(zhí)行不同的任務(wù)時(shí)，發(fā)射波形是如何變化的，這是雷達(dá)波形設(shè)計(jì)和信號(hào)處理很好的仿生模型。Hugh Griffiths教授同時(shí)提出了目前未知的關(guān)鍵問題：蝙蝠是如何進(jìn)行回波信號(hào)處理及如何進(jìn)行目標(biāo)識(shí)別的？給大家留下了思考的空間。
　　Hugh Griffiths教授隨后介紹了IET RADAR SONAR & NAVIGATION及IEEE AESS期刊投稿注意事項(xiàng)。

　　Hugh Griffiths教授的學(xué)術(shù)報(bào)告內(nèi)容豐富，既科普又富有深度。與會(huì)師生認(rèn)真聽取了此次學(xué)術(shù)報(bào)告，并踴躍與Hugh Griffiths教授交流，毛二可院士就超低副瓣波形設(shè)計(jì)及信號(hào)處理、龍騰教授就波形多樣性的實(shí)際應(yīng)用與Hugh Griffiths教授進(jìn)行了深入交談，報(bào)告會(huì)在熱烈討論中結(jié)束。

　　Prof. Hugh Griffiths簡介：

　　Hugh Griffiths holds the THALES/Royal Academy Chair of RF Sensors in the Department of Electronic and Electrical Engineering at University College London, England. From 2006–2008 he was Principal of the Defence Academy of Management and Technology. He received the MA degree in Physics from Oxford University in 1975, then spent three years working in industry, before joining University College London, where he received the PhD degree in 1986 and the DSc(Eng) degree in 2000, and served as Head of Department from 2001 – 2006.

　　His research interests include radar and sonar systems and signal processing (particularly synthetic aperture radar and bistatic and multistatic radar), and antenna measurement techniques. He has published over four hundred papers and technical articles in the fields of radar, antennas and sonar.In 1996 he received the IEEE AESS Fred Nathanson Award (Radar Systems Panel Award), and in 2012 he was awarded the IET A.F. Harvey Prize for his work on bistatic radar.He has also received the Brabazon Premium of the IERE and the Mountbatten and Maxwell Premium Awards of the IEE. He is a Fellow of the IET (previously IEE), Fellow of the IEEE, and in 1997 he was elected to Fellowship of the Royal Academy of Engineering.

　　He serves as President of the IEEE Aerospace and Electronic Systems Society for 2012/2013, He has been a member of the IEEE AES Radar Systems Panel since 1989, serving as Chair from 2007 – 2009, and chaired the Working Group which revised the IEEE Radar Definitions Standard P686 and reaffirmed the Radar Letter Band Standard.
