开发了用于毫米波成像系统的 GaAs 天线耦合肖特基势垒二极管微带阵列。建议采用 Fuko 测试对象和形成单色空间非相干辐射的布置来估计视频系统中此类阵列的成像特性的方法。实验揭示了接收元件的调制传递函数的圆不对称性。这似乎是大多数此类阵列所固有的。在开发基于这些阵列的成像系统时应该考虑到这种不对称性。
Microstrip arrays of GaAs antenna-coupled Schottky barrier diodes for millimeter wave imaging systems were developed. A method for estimating the imaging properties of such arrays in videosystems with Fuko test objects and arrangement for forming the monochromatic spatial incoherent radiation is suggested. Circular asymmetry of modulation transfer function of the receiving elements was experimentally revealed. It seems to be inherent to the majority of such kind of the arrays. This asymmetry is ought to be taken into account during the development of imaging systems on the basis of these arrays.
