本文讨论了一种用于被动辐射成像的大规模W波段焦平面阵列的研制。我们的目标是开发一个40/spl倍/26（1040像素）FPA，以覆盖15/spl度//spl倍/10/spl度/瞬时视场。每个接收机由一个单一的直接检测MMIC，这是一个W波段高增益，宽带宽开关LNA集成肖特基势垒二极管检测器。一个1/spl倍/4焦平面组件，采用线性渐变缝隙天线，被用来作为基本的构建块的焦平面。典型的接收器温度灵敏度为0.4 K，积分时间为10 ms。首次采用自动化组装工艺大批量生产W波段MMIC模块。
This paper discusses the development of a large scale W-band focal plane array (FPA) for passive radiometric imaging application. The goal is to develop a 40/spl times/26 (1040-pixels) FPA to cover 15/spl deg//spl times/10/spl deg/ instantaneous field-of-view. Each receiver consists of a single direct detection MMIC which is a W-band high gain, wide bandwidth switched LNA with integrated Schottky barrier diode detector. A 1/spl times/4 FPA module, employing linearly tapered slot antenna, is used as the basic building block for the FPA. Typical receiver temperature sensitivity is 0.4 K with 10 ms integration time. For the first time, an automated assembly process is used to produce W-band MMIC modules in large volume.
