Advanced architecture for a low cost Multifunction Phased Array Radar

MIT Lincoln Laboratory and M/A-COM are jointly conducting a technology demonstration of affordable Multifunction Phased Array Radar (MPAR) technology for Next Generation air traffic control and national weather surveillance services. Aggressive cost and performance goals have been established for the system. The array architecture and its realization using custom Transmit and Receive Integrated Circuits and a panel-based Line Replaceable Unit (LRU) will be presented. A program plan for risk reduction and system demonstration will be outlined.

I. Introduction

The U. S. Government currently operates seven distinct radar networks providing weather and air traffic surveillance supporting air traffic control and homeland defense missions. Many of these Systems are approaching end of life. A Multifunction Phased Array Radar (MPAR) system has been proposed as the next generation solution for the Nation's weather and air surveillance needs. Full system implementation will result in the deployment of approximately 350 radars. To effectively compete with current mechanically scanned solutions, the MPAR system must achieve an aggressive cost goal of $50 k/m² of array face, while equaling or bettering current performance metrics. To achieve the ambitious cost targets, highly integrated ICs and commercial manufacturing practices are being implemented.
