摘要: 該文討論了在合成孔徑雷達(dá)實(shí)時(shí)成像處理器中,采用子孔徑帶通濾波成像處理方法的方位預(yù)處理的設(shè)計(jì),構(gòu)造了一種用大規(guī)模可編程邏輯器件實(shí)現(xiàn)方位預(yù)處理的電路結(jié)構(gòu)。文中給出了電路應(yīng)用和實(shí)現(xiàn)結(jié)果。可以看到,該電路設(shè)計(jì)具有較高的運(yùn)算效率、集成度、靈活性與可擴(kuò)展性。Abstract: This paper describes the design and realization of the azimuth preprocess in the real-time imaging processor of SAR with programmable logic device by the method of sub-aperture using band-pass filter. The azimuth preprocess circuit implementation and its result are presented. It can be gotten that the circuit performance is satisfactory in operation efficiency, integration degree, implementation convenience and expandability.
