Active perception

Article Abstract:

Active perception or vision involves the generation of modeling and control strategies for data acquisition through active sensor processes that involve the transmission and reception of signals, such as radar and microwaves, or through passive sensors that are used actively and purposefully. The approach requires the modeling of sensors, system modularity, and explicit specification of the initial and final system goals. Models are both local and global. Local models characterized internal procedures and parameters. Global models characterized overall performance and interactions between individual modules. Control strategies involve initialization, processing and task completion. Data-driven bottom-up and knowledge-driven top-down strategies provide respectively, measurement of data the system acquires, and how much acquired data the system uses at a specific stage.

Array technology

Article Abstract:

An overview of current technology in the field of phased array antenna technology. Integrated circuit technology now makes it possible to incorporate high power generation for transmission with low noise pre-amplification on reception. The use of highly integrated solutions has the added advantage of reducing the cost of phased array implementations. Another advantage of integrated circuit technology is that it can be applied at the radiating element level, thus improving antenna performance. Also explored are phase shifters and solid state transmit and receive modules for antenna design.
