【摘要】 本文研究了一种Ka波段弹载多普勒探测前端。该探测前端工作于36GHz连续波模式,收发全相参双天线体制,采用了集成锁相VCO及毫米波倍频放大设计方案,实现了-82dBc/Hz@100kHz的低相噪和大于20dBm发射功率。其整体尺寸为Φ30mm×14.5mm,特别适合于小型弹载平台的应用。更多还原

【Abstract】 In this paper, a kind of Ka-band Missile-borne Doppler Detector is researched. The detection front end works in 36GHz continuous wave mode, transmits and receives fully coherent dual-antenna system, and adopts an integrated phase-locked VCO and millimeter-wave frequency multiplication design scheme to achieve low phase noise of-82d Bc/Hz@100KHz and greater than 20dBm transmit power. Its overall size is Φ30mm×14.5mm, which is especially suitable for small missile-borne platforms.更多还原
