Solicitation Number: N00173-15-R-SE05 Amendment 0004

The purpose of this amendment is to answer a question received from a potential offeror.

Question 1: References: SPECSS Statement of Work, Page 5, IFOV: The IFOV is specified as: < 250 µrad (B) and < 150 µrad (E). Section M, Page 67 reads Sub-factor 1 – The proposal will be evaluated with respect to the soundness of the technical approach for meeting the stated baseline performance metrics and the clarity with which the achievement of those metrics is described.

Please clarify if the definition of IFOV is physical detector width projected into angular object space. By using a definition of the overall system spatial sampling resolution projected into object space, enhanced capability is possible so long as NEDT and NEI with the real system PVF (optics, jitter, algorithm, etc.) is satisfied. Please provide the Government’s definition for IFOV that will be used to evaluate the soundness of the Product 1 Technical Proposal/approach?

Answer: For this purpose the IFOV is defined only as the physical detector width projected into angular object space, or equivalently the sensor angular field of view divided by the number of pixels covering it for an idealized system with no field distortion. Optical system performance metrics such as field distortion, MTF, and optical point spread function will also be used to assess the technical soundness of the proposed approach.
