This project directly supports federal spectrum management, usage assessments, interference resolution, propagation research support and other agency needs by developing and implementing a 4th generation Radio Spectrum Measurement System (RSMS) equipped with state-of-the-art instrumentation, measurement methods, and analysis capabilities. The present RSMS hardware is third generation (RSMS-3). Although RSMS-3 is a powerful measurement tool, its status as a state-of-the-art spectrum measurement system is threatened by rapid advances in radio technology. Therefore, a fourth-generation upgrade has been proposed and approved: RSMS-4. New broadband measurement and calibration capabilities are needed to assess the effects of emerging technologies such as time-domain-based ultrawideband (UWB) and spread-spectrum systems. Other capabilities needed include signal identification, direction-finding, operation at higher frequencies, and remote control. Challenges that await in the near future include measurements of adaptive systems that can very rapidly change their channel usage, modulation bandwidths, or antenna pattern. The use of the new RSMS will enhance the Nation's technical capability to make spectrum-related measurements at wider bandwidth and higher frequencies. Furthermore, the new capability will be more adaptable to user needs simply because commercial and specialized test equipment to be used will be configured locally or remotely via computer data interfaces. The on-board power generation will be quieter (electromagnetically) and the measurement enclosure better shielded to improve the capability to make reliable measurements of weaker signals and to allow the use of the system to make limited measurements of broadband radio noise characteristics.
