介绍了一种采用低成本SiGe技术实现的紧凑型、轻量化、柔性连续波(CW)毫米波主动成像系统。它基于一个接收器(RX)芯片，具有覆盖158到165 GHz频段的零中频(IF)正交混频。该外差成像系统提供110分贝的动态范围，并产生高成像对比度。使用这种毫米波成像系统，可以利用传输波的幅度和相位信息。8 GHz的可用带宽可用于雷达传感应用中的扫频源，提供三维图像重建的能力。
This paper presents a compact, low-weight and flexible continuous wave (CW) millimeter-wave (mmWave) active imaging system implemented in low-cost SiGe-Technology. It is based on a receiver (RX) chip with zero-intermediate frequency (IF) quadrature mixing covering the 158-to-165 GHz band. This heterodyne imaging system provides dynamic range of 110 dB and yields high imaging contrast. Using this mmWave imaging system it is possible to exploit both the magnitude and the phase information of the transmitted wave. The available bandwidth of 8 GHz can be employed for swept sources in radar sensing applications offering the capability of 3D image reconstruction.
