| 摘 要： | 提出了毫米波ＦＭＣＷ收发组件设计模型。针对这类系统特有的１／ｆ噪声和ＦＭ ＡＭ变换噪声，设计了一种新颖的外差型９４ＧＨｚ和３５ＧＨｚＦＷＣＷ收发组件。线性调频带宽１０００ＭＨｚ，发射功率２０～５０ｍＷ，目标检测灵敏度－１５０ｄＢｃ／Ｈｚ。该设计较常规的“零拍型”检测灵敏度改善２０ｄＢ。对同等检测距离，可节省发射功率一个数量级以上。

| Abstract: | A model to design mm wave FMCW transceiver has been proposed. Taken aim at reducing the 1/ f noise and FM AM conversion noise occurred in this kind of systems essentially, the novel heterodyne 94 GHz/35 GHz FWCW transceiver with 1 000 MHz of FM linear bandwidth and more than 20～50 mW of transmitting RF power as well as -150 dBc/Hz of sensitivity to detect objects has been developed. In the result, the S/N was 20 dB better than the convertional designed homodyne FWCW modules and therefore more than one order of transmitting RF power can be reduced for the same detected ranges. |
