【摘要】：連續(xù)波雷達(dá)系統(tǒng)對發(fā)射機輸出信號的頻譜純度要求比較苛刻,由于擔(dān)心使用開關(guān)電源后電源紋波等影響最終輸出信號質(zhì)量,傳統(tǒng)的大功率連續(xù)波發(fā)射機一般采用飽和電抗器穩(wěn)壓或電動調(diào)壓器預(yù)穩(wěn)壓的穩(wěn)壓形式和400Hz十二相整流濾波或有源線性濾波的濾波形式。本文研究和設(shè)計了一種采用開關(guān)電源形式的連續(xù)波速調(diào)管發(fā)射機。首先,討論了連續(xù)波速調(diào)管發(fā)射機的發(fā)展和特點;然后,給出了發(fā)射機的組成和基本原理;接下來根據(jù)系統(tǒng)要求,進(jìn)行了整機方案的設(shè)計;并從工程實踐的角度,對各分機展開詳細(xì)設(shè)計;最后進(jìn)行了整機性能測試,結(jié)果表明該發(fā)射機工作穩(wěn)定,性能指標(biāo)良好。同時,本文還討論了一些進(jìn)一步研究工作需要改進(jìn)和考慮的地方。
[Abstract]:The frequency spectrum purity of the transmitter's output signal is demanding by the continuous wave radar system. Because of the worry that the ripple of the power supply after the use of the switching power supply will affect the final output signal quality, The traditional high power CW transmitters generally use the saturable reactor voltage regulator or the electric voltage regulator pressure-stabilized voltage filter and the 400Hz 12 phase rectifier filter or active linear filter filter. In this paper, we study and design a kind of filter. A continuous wave klystron transmitter in the form of a switching power supply. First, The development and characteristics of the continuous wave klystron transmitter are discussed. Then, the composition and basic principle of the transmitter are given. Then, according to the requirements of the system, the design of the whole machine scheme is carried out, and from the point of view of engineering practice, The detailed design of each extension is carried out. Finally, the performance of the transmitter is tested. The results show that the transmitter works stably and the performance index is good. At the same time, some improvements and considerations for further research work are also discussed in this paper.
