    The concept of system of systems (SoS) and the challenges ahead to extend systems engineering (SE) to system of systems is introduced. The birth of a new engineering field may be on the horizon - system of systems engineering (SoSE). A SoS is a collection of individual, possibly heterogeneous, but functional systems integrated together to enhance the overall robustness, lower the cost of operation, and increase reliability of the overall complex (SoS) system. Having said that, the field has a large vacuum from basic definition, to theory, to management and implementation. Many key issues like architecture, modeling, simulation, identification, emergence, standards, net-centricity, control, etc., are all begging for attention. In this review, we go through all these issues briefly and bring the challenges to the attention of interested readers. We will also indicate the existence of an introduction consortium, of interested groups who are getting together to help realize these problems and try to find solutions. View full abstract»

    Radar systems were initially limited to military applications, but today most people encounter radar applications everyday. Given the broad range of applications, a variety of radar types and technologies have emerged to meet unique needs. This paper discusses about the latest advances on system performance and testing of radar systems. When performing characterization of a radar receiver design, a variety of signals are required to accurately recreate the operational environment. This paper will review the test signal environment needed for evaluation of various modern radar systems. Performance considerations in terms of signal source fidelity and spectral purity will also be investigated. View full abstract»

    MIT Radiation Laboratory-or Rad Lab - was the center of microwave radar development in the US during World War II. Rad Lab designed essentially all of the microwave radars used in that war. Additionally, it created the fundamental knowledge, theory, circuits, and components used in those systems. GCA (ground control of approach, radar system for landing aircraft at night and in bad weather) was one of several programs in Division 7 - all creations/inventions of Professor Luis Alvarez in the lab. The author has explained his experience in the Rad lab on developing the project with his colleagues and boss. View full abstract»

  • Analysis of surface micro machined RF MEMS phase shifters

    Development of low loss radio frequency micro-electro-mechanical (MEMS) phase shifters for radar and telecommunication applications is presented. Numerical simulation results using electromagnetic simulator tools (CST - Germany) along with fabricated wafer level measurement results of two distributed MEMS phase shifters are presented herein for upstate capacitive bridge position. The distributed MEMS phase shifter consists of coplanar waveguide (CPW) transmission line and several MEMS bridges loading capacitively on transmission lines to create a slow wave structure. Two configurations of phase shifters are presented. 1) Conventional distributed MEMS transmission line (DMTL) 2) coplanar waveguide - microstrip - coplanar waveguide (CPW-MS-CPW), with microstrip as the transmission line and CPW as input and output line. The electromagnetic simulation results of gap height variation to change the phase velocity and, in turn, phase shift is presented. Work is underway to vary the gap height between transmission line and the bridge, applying the actuation voltage to bridge capacitors, which, in turn, will vary the bridge capacitance, changing the phase velocity on fabricated phase shifters. The match between simulated results and wafer level measurements are encouraging and will be presented in the full paper. Work is also underway to validate wafer level measurements along with numerical simulation using circuit models using circuit simulator. The custom model libraries for phase shifters are being developed. The results are encouraging. View full abstract»

  • UWB radar for human being detection [same as "UWB radar for human being detection", ibid., vol. 21, n. 11, 06]

    UWB radar for detection and positioning of human beings in a complex environment has been developed and manufactured. The novelty of the radar lies in its large operational bandwidth (11.7 GHz at -10 dB level) combined with high time stability. Detection of respiratory movement of a person in laboratory conditions has been demonstrated. Based on experimental results, human being radar return has been analysed in the frequency band from 1 GHz to 12 GHz. The novel principle of human being detection is considered and verified experimentally. View full abstract»
