PASSIVE MILLIMETER WAVE FOCAL PLANE IMAGING METHOD COMBINED WITH INTERFEROMETRY

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 millimeter-wave focal plane array （FPA） and the images are not clear,a focal plane imaging method combined with interferometry was proposed to generate more image pixels than the conventional FPA imaging methods. By combining coherent and incoherent technologies,the method can increase the number of image pixels. Therefore,the spatial resolution of passive millimeter-wave multi-beams imaging was improved. Both theoretical analysis and simulation results demonstrate the effectiveness of the method.
