摘　　要：快前沿射频脉冲发射是固态有源相控阵可实现的优势功能。分析了X波段固态有源相控阵实现快前沿射频脉冲发射的必要条件,包括激励传输、功率放大、定时同步和孔径渡越等影响因素及设计要点。相应的分析结论应用于某型X波段固态有源相控阵的样机研制,最终实现了数千个固态有源通道的快前沿射频脉冲的高效空间合成,合成射频脉冲前沿低于5 ns,验证了分析与设计的有效性。Fast leading-edge RF pulse emission is an advantageous function of solid-state active phased arrays.In this paper,the conditions of realizing fast leading-edge RF pulse emission are analyzed,including influences anddesign points of RF excitation transmission,power amplification,timing synchronization and aperture fill time.Theconclusions are applied to a prototype design of an X-band solid-state active phased array,followed by validation test.RF pulses emitted by thousands of solid-state active channels are spatially combined into one,with the leading-edgeshorter than 5 ns,which validates the analysis.
