Innovative 2K x 2K Dual Band Readout Integrated Circuit for MDA Applications

Nova Sensors proposes the development of a new 2K x 2K dual-band readout integrated circuit (ROIC) that will be specifically tailored for use in MDA applications. We propose incorporation of on-FPA features that streamline the use of the resulting dual-band focal plane array (FPA) data for missile detection, tracking and spectral discrimination applications. In cooperation with QmagiQ and Lockheed Martin Santa Barbara Focalplane (SBF), Nova will produce a preliminary design for this dual band ROIC in the Phase I effort. The ROIC will also accommodate use of other detector materials, but the superior uniformity and “bandgap engineered” features of QmagiQ’s multiple quantum well (QWIP) material will be an important element of the proposed effort. Lockheed Martin SBF has indicated their support for transitioning this new technology into fielded systems. A variety of on-FPA processing operations are proposed that will help to optimize the implementation of such very large format dual band FPAs; these include on-FPA spectral differencing and ratioing operations as well as on-chip analog-to-digital (A/D) conversion.
