Advances and Breakthroughs in Radar and Phased Arrays
Abstract
New systems: S/X-band AMDR: GaN AESA, 30 times sensitivity and tracks as SPY-1D(V). 3, 4, 6 faced “Aegis” systems: USA, Israel, China, Signaal-Thales, Japan, Australia. System Upgrade: Patriot now 2016 state-of –art radar, GaN Active Electronically Scanned Array (AESA), 360o coverage without rotating antenna; Low Cost Packaging: Using Commercial Off-the-Shelf (COTS) components; Extreme MMIC: 32 element 60 GHz T/R array on chip, future cost few dollars. Digital Beam Forming (DBF): A/D for every element: Elta (Israel), CEA (Australia), Thales (France), Raytheon developing mixer-less direct RF A/D having >400 MHz instantaneous bandwidth, reconfigurable between S and X-band. Materials: GaN can put 5X to 10X power of GaAs in same footprint, 38% less costly, 100 million hr MTBF. MIMO (Multiple Input Multiple Output): Where it makes sense and how conventional arrays can do as well. Metamaterial Antennas: $1K (goal) 20 GHz and 30 GHz ESAs. Very Low Car Array Radar: $100s. MEMS: for Phase shifters and flying insect robots; Printed Electronics: Low cost 1.6 GHz printed diodes (goal 2.4 GHz). Electrical and Optical Signals on Same Chip; IR transparent in silicon. Graphene and Carbon Nanotube (CNT): Potential for Terahertz transistor clock speeds, Moore’s Law marches on; Spintronics: Could revolutionize computer architecture away from John von Neumann model. Memristors: Allow one to do what human brain does in a shoe box instead of city sized computer. Biodegradable Arrays of Transistors or LEDs: Imbedded under skin for detecting cancer or low glucose. Quantum Radar: See stealth targets.
