Northrop Grumman Systems Corp

SWIRP COMPACT SUBMM-WAVE AND LWIR POLARIMETERS FOR CIRRUS ICE PROPERTIES. THIS EFFORT COVERS THE NORTHROP GRUMMAN AEROSPACE SYSTEMS (NGAS) PORTION OF THE WORK BEING PERFORMED IN SUPPORT OF THE SWIRP PROGRAM FUNDED BY THE EARTH SCIENCE TECHNOLOGY OFFICE (ESTO) INSTRUMENT INCUBATOR PROGRAM (IIP) 2016 AND NGAS TASKS IN SUPPORT OF IIP 2016 COMPACT-WAVE AND LONG-WAVE INFRARED (LWIR) POLARIMETERS FOR CIRRUS ICE PROPERTIES (SWIRP). # ONE (1) 220 GHZ DUAL-POLARIZED RECEIVER # TWO (2) 680 GHZ DUAL-POLARIZED RECEIVERS # ONE (1) MINIATURIZED BEARING AND POWER TRANSFER ASSEMBLY # ELECTRICAL/DATA INTERFACE DOCUMENTATION FOR ITEMS 1-3 # MECHANICAL INTERFACE CONTROL DOCUMENT AND EXTERIOR CAD MODELS FOR ITEMS 1-3 THE SWIRP INSTRUMENT IS COMPRISED OF EIGHT PRIMARY SUB-SYSTEMS. NAMELY, 1. 680 GHZ DUAL-CHANNEL (HORIZONTALLY AND VERTICALLY POLARIZED, FROM HERE ON REFERRED TO AS H-POL AND V-POL) RECEIVERS WITH INTEGRATED ANTENNA FEED HORN 2. 220 GHZ DUAL-CHANNEL (H AND V-POL) RECEIVER WITH INTEGRATED ANTENNA FEED HORN 3. MINIATURIZED BEARING AND POWER TRANSFER ASSEMBLY (MINI-BAPTA) 4. LONGWAVE INFRARED CHANNELED SPECTRO-POLARIMETER (IRCSP) 5. ANTENNA REFLECTORS AND CALIBRATION TARGETS (I.E. PRIMARY, SECONDARY AND COLD-SKY REFLECTORS) 6. POWER CONDITIONING AND DISTRIBUTION SYSTEM 7. ANALOG TO DIGITAL CONVERTER (ADC) 8. COMMAND AND DATA HANDLING (C&DH) SYSTEM. NGAS (FROM HERE ON REFERRED TO INTERCHANGEABLY AS THE CONTRACTOR OR NORTHROP GRUMMAN) WILL BE RESPONSIBLE FOR THE DESIGN AND MANUFACTURING SUB-SYSTEMS 1-3, UNIVERSITY OF ARIZONA (UOA) WILL BE RESPONSIBLE FOR SUB-SYSTEM 4 AND GSFC WILL BE RESPONSIBLE FOR 5-8 AS WELL AS INTEGRATION AND TESTING OF THE INSTRUMENT. THE CONTRACTOR SHALL DESIGN, SIMULATE AND LAYOUT A CHIPSET FOR A DIRECT DETECTION RECEIVER. THE CONTRACTOR SHALL PERFORM DC AND RF MEASUREMENTS TO VALIDATE WAFER ELECTRICAL PERFORMANCE. THE CONTRACTOR WILL DESIGN A 680 GHZ DUAL-POLARIZED RECEIVER IN A COMPACT, LOW DC FORM FACTOR OPTIMIZED FOR PLACING IN A 2-ELEMENT ARRAY. THE CONTRACTOR WILL ALSO DESIGN A 220 GHZ DUAL-POLARIZED RECEIVER IN A COMPACT, LOW DC FORM FACTOR AND THE CONTRACTOR WILL PROVIDE ANALYSIS ON A MINI-BAPTA MEETING THE SWIRP PROGRAM NEEDS.
