Background and aim: Microwave radiations are one of the most environmental workplace factors that exposed too many workers. In microwave spectrum, radar frequency with 1-300 GHz range have varied applications such as satellite, communications, military, Network, navigation, air-traffic Control, navigation, marine and weather. Uncontrolled occupational exposure to radar radiation caused to vari...
CCC-r chart extended approach of CCC charts, is a technique applied when nonconforming items are rarely observed. However, it is usually assumed that the inspection process is perfect in the implementation control charts imperfect inspections may have a significant impact on the performance of the control chart and setting the control limits. This paper first investigates the ...
one of the problems in detecting radar targets is the variation of target cross section due to aspect angle; which is named as target fluctuation. this perfectly depends on target geometry and transmitted wavelength and can cause significant loss of detection. one of the solutions to this is improving the radar range resolution. stepped frequency is one of the signals that can improve the range...

By increasing the applicability of ground-based SAR (GBSAR) systems in geoscience and remote sensing, the development and evaluation of new systems have gained attention. GBSAR systems can be utilized for monitoring areas that are hard to or cannot be seen by the airborne or spaceborne systems. Furthermore, they have better spatial and temporal resolutions and are cost-effective and easy to imp...
In this paper, the use of quantum technology in the radar system and the advantages of these radars as compared to classical radars have been analyzed. In the beginning, briefly, we present the basic structure of the theory of quantum electrodynamics, and then the role of photon in this theory and photon interactions is presented. In the next step, the most general form of the quantum radar cr...
Sustainable buyer–supplier relationship (SBSR) capability is a dynamic or relational that considered as the key condition for achieving sustainable competitive advantage through both buyer and its suppliers investing their heterogeneous resources. To accurately measure develop from sustainability perspective, this study first proposes an effective evaluation framework based on view triple-botto...
