TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
We propose to design a general purpose reconfigurable wide bandwidth spectrometer
for use in NASA's passive microwave missions, deep space network and radio astronomy.
In Phase I, we will design and build a low power, low cost real time FPGA based
spectrometer board that will analyze a 3 GHz bandwidth signal with 16,384 channels.
Utilizing 3 Gsample/sec 8 bit ADC's and Xilinx Virtex 4 FPGA's, the proposed spectrometer
can also be configured to analyze a pair of signals with 1.5 GHz bandwidth each,
or four signals of 750 MHz bandwidth each. A Polyphase Filter Bank (PFB) will be
implemented instead of a large FFT, because the PFB has excellent out of band rejection ($> 80$ dB),
preventing strong RFI from contaminating adjacent bands.
In Phase II, we will space qualify the spectrometer, provide significantly higher bandwidth
capabilities, and add high speed output, and consider an ASIC implementation for lower-power space-based applications.
Techne instrumentation has flown on Rosetta, PERSI, and several soundong rockets.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
NASA will be able to utilize the Phase I ground based spectrometer
for prototyping space based passive microwave instruments, especially
focal plane array and multibeam receivers, for antenna holography,
spectroscopy at NASA's deep space network, small array imaging systems,
and for K12 education at NASA's GAVERT radio telescope.
The Phase II spectrometer can be used for space based microwave missions,
beam forming, RFI mitigation, SETI, and for a large array imaging FX correlator
at the next generation DSN.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
We will make the Phase I low cost spectrometer available to the radio astronomy community
for a wide variety of applications, including multibeam spectroscopy (eg: HEAT, MAS),
holography, IR and sub-mm heterodyne spectroscopy, CMB resonating bolometer experiments,
and small educational radio telescopes at high schools and universities.

The phase II spectrometer with 10GBe/infiniband outputs can be used for beam forming, pulsar timing and searching,
reionization experiments, adaptive RFI mitigation, very long base line interferometry (Mark 5C VLBI for geodesy and astronony),
and large imaging correlators such as those needed for SKA, ATA, LOFAR, LWA, PAST and transient searches.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
