Design and testing of the passive mm-wave sensor operating in 88-100 GHz range is reported. The scanning part of this sensor is based on a heterodyne configuration with a bandwidth up to 12 GHz and NF = 9-10 dB. It can receive like noise signals that are typical for passive mm-wave imaging. Depending on the antenna system the sensor can be configured for(More)
Modeling of real time software systems (RTSS) consist of different components with UML 2. 0 leads to a design model using various diagrams. To get a consistent model, a consistency concept for different diagrams type is needed that takes into account real time constraints. Ensuring consistency of The Unified Modeling Language (UML) model is very crucial as(More)
—Forward scattering effects have been studied and compared when nonhomogeneous medium is illuminated by coherent and quasi-noise sources operating in mm-wave and microwave ranges. Double-layers dielectric structure simulating Fabry-Perot resonator properties was employed to develop a relevant model used for comparing transmittances of both coherent and(More)
