Title: Radar, Phased-Arrays, Metamaterials, Stealth, Anti-Stealth, Ultra-Wideband, Cognitive Adaptivity, Mimo-- Basics and Breakthroughs
Abstract: This tutorial covers recent developments in phased arrays updated to 2018. It provides a concise, introductory level survey of the fundamentals without dwelling on extensive mathematical derivations or abstruse theory. Instead a physical understanding is given. Covered in easy terms will be sidelobe cancellation (SLC), COGNITIVE ADAPTIVE ARRAY PROCESSING (CAAP) which provides full adaptive array processing without suffering its computation complexity. Finally, Space-Time Adaptive Array (STAP) for airborne platforms will be explained and related to the displaced phase center antenna (DPCA).
This course is intended for the engineer or scientist not familiar with phased-array antennas as well as the antenna specialist who wants to learn about other aspects of phased-array antenna systems as well as get the latest developments in array systems, such as: MIMO, metamaterial arrays, Extreme MMIC arrays, stealthing and cloaking, COGNITIVE ADAPTIVITY. The major emphasis will be on the system aspects of phased-arrays.
BASICS of Passive Electronic Scanned Arrays (ESAs) and Active Electronic Scanned Arrays (AESAs): Phase Steering, Time Delay Steering, Subarraying, Array Weighting, Monopulse, Duplexing, Array Thinning, Embedded Element, Array Weighting, Array Factor, Triangular vs Square Lattice, Tour of COBRA DANE ESA and PAVE PAWS AESA (both 6 stories high) via color slides. Limited and hemispherical scan phased arrays.
RECENT AESA DEVELOPMENTS: Patriot upgrade to 2016 state-of-the-art AESA; S-band AMDR AESA radar provides 30X sensitivity of SPY-1D(V). LOW COST PACKAGING: AESAs using commercial-off-the-shelf (COTS) hardware and packaging. EXTREME MMIC: Whole 256 element phased array on single chip at 60 GHz. DIGITAL BEAM FORMING (DBF): Reduces search power and time by almost a factor of two; Makes cognitive radars realizable; enables ultra low antenna sidelobes; MOORE’S LAW: Potential future continuation of Moore’s Law via Spintronics, Memristors, Graphene, Quantum Computing. VERY LOW COST RADARS: for cars, UAVs, watch cell phones.
METAMATERIALS: low cost 2-D ESAs for satellite internet communications (at 10-15 GHz); for cell towers, for cars and UAV radars; Stealthing by absorption and by cloaking; wideband fractal metamaterials; Army 250-505 MHZ conformal antenna to replace tall whip antennas. WIDEBAND LOW PROFILE ANTENNA: 20:1 bandwidth.
COGNITIVE ADAPTIVE ARRAY PROCESSING (CAAP): Applied to jammers. Tremendous advantages over classical adaptive processing detailed. STAP and DPCA. SLC.
QUANTUM RADAR: Has potential to defeat stealth targets. LOW COST PRINTED MICROWAVE ELECTRONICS: 1.6 GHz printed diodes achieved (goal 2.4 GHZ). ELECTRICAL AND OPTICAL SIGNALS ON SAME CHIP: Will allow data transfer at the speed of light. BIODEGRADABLE ARRAYS OF TRANSISTORS OR LEDs: Imbedded under skin for detecting cancer or low glucose.
New MIMO (MULTIPLE INPUT MULTIPLE OUTPUT) Radar: Explained in simple physical terms instead of with heavy math. Covered are performance, waveforms, signal processing load, ability to handle jamming, performance re conventional radars. Where it makes sense to use: OTH, automobile radars, to combining existing radars to increased performance.
