Abstract:

Sensor Hardware Basic hardware research for concurrent dual-band dual-polarization radar was conducted, resulting in various novel architectures with unprecedented performance. The system is designed using a 0.18-microns SiGe BiCMOS process in single chips and is extremely small. The entire system is estimated to have a size of only 12mmx8mm and 5cmx5cm without and with 6-element antenna array, respectively. Various components and subsystems, e.g., the concurrent dual-band transmitter and tri-band tri-output synthesizer, have been completely developed or designed with unprecedented performance. Signal Processing and Software The research and development of signal processing and software for the multiband sensor was completed. New hardware HW software SW codesign paradigm was developed for the purposes of adaptive processing of cross-polarization sensor data obtained from multiple sensor modalities aimed at collaborative high-resolution sensing, detection, localization and identification of point-type and distributed targets in urban environments. The unified HWSW codesign techniques capable of operation in uncertain operational scenarios for a variety of admissible sensor array configurations outperform the existing adaptive radar imaging algorithms both in resolution and convergence rate. The elaborated Virtual Remote Sensing Laboratory SW was integrated with the prospective synthesized simulated sensor HW model for demonstration of the superior capabilities of the overall prospective multimode sensor system via extensive simulation studies.
