Then after analyzing the heat conduction in laser diode array, we simply simulate the transient thermal behavior of high power laser diode array and build a two dimensional static model of temperature distribution of it by fem ( finite element method )
接著分析激光器陣列中熱的傳導,簡單的模擬工作工程中瞬態溫度的變化。然後通過有限元分析法,建立二維溫態分佈,得到穩態工作時,大功率激光器陣列中晶元和載體的溫度的空間分佈。This paper goes on with analysis of the phased array radar calibration theory and compare of different schemes, then the best is adopted. 2 mhz digital circuit mainly composed of dds ( direct digital synthesis ) chip, which carries out the shift of the phase and the limit of the amplitude, has been designed and debugged successfully. it is used to substitute for the conventional phased shift circuit and amplitude limiting circuit which work at the radio frequency, so the all - digital transmit channel of phased shift array radar is achieved
本論文研究的重點是:針對傳統相控陣雷達系統收發( t r )組件中的移相和限幅功能均在射頻段完成,大膽利用直接數字合成( dds )晶元組成頻率在2mhz左右的數字電路代替傳統相控陣雷達在射頻段進行移相和限幅的電路,從而組成全數字發射通道,使對相位和幅度的控制和調試更方便快捷,並設計具體的電路驗證此方案的可行性。Abstract : to against the fact of the commercial available white noise generators are very expensive which is not good for general operations, a simple and effective limited band white noise generator is design. the generator is using the feature of dual polarity transistor, i. e., the power spectrurn density of particulate noise is not related to frequency in very wide band and close to white noise. the concrete circuit is also given
文摘:針對市售白噪聲發生器價格昂貴,不利於一般場合使用的問題,介紹利用雙極性晶體管散粒噪聲功率譜密度在非常寬的范圍內與頻率無關,屬白噪聲這一特性,設計了一種簡捷、有效的限帶白噪聲發生器,並給出了具體電路。
