1.1 This test method covers the measurement of the effective surface roughness of an opaque reflecting surface as determined by the total integrated light scattering (TIS).

1.2 Applications:

1.2.1 This test method...

It is known that detecting small moving objects in astronomical image sequences is a significant research problem in space surveillance. The new theory, compressive sensing, provides a very easy and computationally cheap coding scheme for onboard astronomical remote sensing. An algorithm for small m...

The transmission upper limit of a double-layer frequency selective surface (FSS) with two infinitely thin metal arrays is presented based on the study of the general equivalent transmission line model of a double-layer FSS. Results of theoretical analyses, numerical simulations and experiments show ...

The features of information technology (IT) are discussed first. On this basis, the features of space information technology (SIT) are presented and SIT is elaborated in five categories. The popularization of SIT is an informatization process and will promote the industrialization of national econom...

The path loss analysis model based on 5 rays in vacancy indoor environment is proposed. The relationship between multipath overlapping and the path loss is analyzed mathematically. Time-domain technique is introduced to compute reflection coefficient in a very short time interval. A 5 rays path loss...
