针对被动毫米波焦平面阵列中相邻馈源波束存在的重叠区域, 采用相关的方法对相邻馈源的输出进行相关 接收, 产生了新的像素信息, 提出了一种融合干涉测量的焦平面成像方法.该方法将相干和非相干技术进行有效融 合, 增加了被动毫米波多波束成像像素的数量, 提高了成像分辨率.理论分析和仿真实验都表明该方法是有效的.

Aiming at the problems that there exisited overlap regions between the beams of adjacent feeds in passive milli- meter-wave focal plane array (FPA) and the images are not clear, a focal plane imaging method combined with interferome- try was proposed to generate more image pixels than the conventional FPA imaging methods. By combining coherent and in- coherent technologies, the method can increase the number of image pixels. Therefore, the spatial resolution of passive mil- limeter-wave multi-beams imaging was improved. Both theoretical analysis and simulation results demonstrate the effective- ness of the method.
