Abstract:

The wirelessly networked opportunistic digital array radar WNODAR system combines opportunistic phased array and aperstructure concepts. The array elements contain stand alone transmit receive TR modules with no hardwire connections other than prime power and are wirelessly networked to a central controller and processor unit. A full scale WNODAR operating in the VHFUHF frequency bands 300 MHz exhibits many favorable properties, which make the system suitable for ballistic missile defense BMD early warning radar EWR applications. In order to validate the WNODAR concepts, demonstration arrays consisting of TR modules realized using field programmable gate array FPGA technology are developed. The demonstration units are frequency scaled from the projected VHFUHF frequency range to S-band 2.4 GHz to make use of the abundance of commercial off the shelf COTS wireless communication components. This research primarily relates to the development of a demonstration TR module and the evaluation and characterization of component devices. Design, analysis and simulation of an eight element demonstration array using MATLAB and CST Microwave Studio were conducted to examine expected array beam patterns.
