WinRad: a spectroradiometric modeling program for remote imaging sensor
WinRad is a computer software program for analytically modeling and
simulating the performance of imaging spectroradiometers spanning the
ultraviolet through infrared wavelengths. It is innovative because it will
provide a low-cost, easy-to-use tool that is currently unavailable to
scientists and engineers developing advanced electro-optic remote sensors.
The Phase I objectives are to develop the specifications for WinRad's
modeling and simulation capabilities, graphical user interface, and object-
oriented design; and to develop a software prototype that demonstrates the
specified computational and performance requirements. Achieving these
objectives will demonstrate the feasibility of successfully completing the
development of WinRad in Phase II. NASA and the aerospace community in
general will benefit because WinRad will significantly simplify radiometric
sensor modeling and simulation, which until now has been very cumbersome and
time consuming, and in many cases will eliminate the requirement to develop
separate software for each new sensor. WinRad will also create a standard for
exchanging spectroradiometric modeling and simulation information among
scientists and engineers. To provide the largest possible market for WinRad,
it will be developed under the Microsoft Windows operating system, which runs
on most PCs and high-performance RISC workstations.
The software package WinRad has great potential for sales in the commercial
market, because of the increasing interest in remote sensing systems and the
development of new electro-optic sensors (both environmental and defense-
related). Thus far, companies have either been unwilling or unable to put
forth the capital required to bring such a program to market, and the proper
development tools and hardware platforms have only recently become available
to support this undertaking. Conceptual demonstrations of WinRad by RAI at
two electro-optic conferences in 1993 indicated a strong interest by the
remote sensing and aerospace community. Sales of this software would be
significant within NASA (particularly GSFC and SSC), other federal agencies
(DoD, NOAA, NIST), universities, and both domestic and foreign companies.
