Amazing Breakthroughs and Trends in Phased Arrays and Radars

Life Members & AESS – 4:00 – 5:15 PM Wednesday, 25 March

Amazing Breakthroughs and Trends in Phased Arrays and Radars (IEEE AESS Distinguished Lecture)

Dr. Eli Brookner, Raytheon Company (retired)

Covered will be recent truly amazing developments and breakthroughs in metamaterials, graphene, digital beam forming, micromachining, low cost arrays and signal processing and the impact of these advances on radar and phased arrays. Metamaterials: Material custom made (not found in nature): electronically steered antenna not using phase shifters at 20 and 30 GHz demonstrated (still remains to prove low cost and reliability); 2-20GHz stealthing by absorption simulated using >1 mm coating; target made invisible over 50% bandwidth at L-band; Graphene and Carbon Nanotube (CNT): Potential for Terahertz transistor clock speeds, manufacture on CMOS demo’d, could allow Moore’s law to march forward using present day manufacturing techniques; Synaptic Transistors: Learns like human brain synapse, analog computing could be in our future; Extreme MMIC: 4 T/R modules on single X-band chip, ~$10 per T/R module; on-chip built-in-self-test (BIST) at W-Band; wafer scale integration at 110 GHz of whole array; Printed Electronics: Low cost printing of RF and digital circuits using metal-insulator-metal (MIM) diodes and 2D MoS₂ ink; Electrical and Optical Signals on Same Chip: Both electricity and light simultaneously transmitted over a silver nanowire combined with single layer 2D MoS₂, could be a step towards transporting on computer chips digital information at the speed of light. COSMOS DARPA program: Allows integration of III-IV, CMOS and optics on one chip without bonded wires; Digital Beam Forming: AESAs with A/D for every element channel; Raytheon developing element level mixer-less direct RF A/D having >400 MHz instantaneous bandwidth, reconfigurable between S and X-band; Low Cost Packaging: Raytheon and Lincoln Laboratory independently developing respectively X-band and S-band low cost flat panel arrays using COTS type PCBs; Very Low Cost Systems: Valeo-Raytheon low cost, $100s only, car 25 GHz 7 beam phased array radar; DARPA goal, $1/element 94 GHz array; MEMS: reliability reaches 300 billion cycles without failure, can reduce T/R module count by factor of 2 to 4; MEMS Piezoelectric Material = piezoMEMS: for flying insect robots; MIMO (Multiple Input Multiple Output): contrary to what is claimed MIMO array radars do not provide 1, 2 or 3 orders of magnitude better resolution and accuracy than conventional array radars; MIMO does not provide better barrage-noise-jammer, repeater-jammer or hot-clutter rejection than conventional array radars; Additional Advances: Biodegradable array of transistors or LEDs for detecting cancer or low glucose, can then dispense chemotherapy or insulin; Can now grow functioning non-rejecting kidney and heart for rats; New polarizations, OAMs, unlimited data rate over finite band using new polarizations??
