2. the image rejection mixer is composed of two unit mixers, rf is halved as two parts in quadrature; lo is halved as two parts in phase; if is synthesized in quadrature
   鏡頻抑制混頻器包含兩個單元混頻器,射頻正交功分,本振同相功分,中頻正交合成。
3. conversion of signals from if analog into digital samples carrying phase and amplitude information has been traditionally implemented in the form of two parallel if to baseband converters operated in quadrature each followed by a / d converters which thus provide digitized in-phase ( i ) and quadrature ( q ) components
   對于傳統雷達信號接收機，幅相一致性較差。為克服這一問題，人們考慮在中頻，甚至射頻就對信號數字化，再在數字域內進行解調。同樣需要高速的數據采集系統才能滿足要求。
