The major improvements to ShipIR/NTCS (v3.2) include:

• full-spectral 2D (φ,θ) directional irradiation used to predict sea surface radiance, target surface radiance, and target surface temperature prediction,

• new three flow regime (stagnation, tangential, separated) flow convection heat transfer model capable of handling high-Re (Reynolds Number) values in the range 10⁷ to 10⁹,

• automatic triggering of a new atmosphere condensate model when predicted surface temperatures dip below the current local dew-point temperature,

• new option to have radiative surface properties of any wetted surfaces (i.e., in condensation or user-TBC with Tsea) replaced with a standard water-film property model,

• new 16-bit precision and off-screen rendering version of OpenGL (in software under Linux),

• ability to create + analyse signature within pre-defined target analysis groups, containing a collection of surface patches and/or exhaust stacks (plumes),

The following minor improvements and bug fixes made since ShipIR/NTCS (v3.2) and are now released as part of ShipIR/NTCS (v3.2d):

• the sea geometry grid has been refined near the visual horizon (earth tangent) to minimize previous errors associated with earth-curvature,

• the previous minimum observer field-of-view (FOV) of 0.1° has now been reduced to 0.001°,

• corrections have been made to the Auto-Apply water-film option in the File|Advanced dialogue of Edit|Target,

• a new version of ravfac (radiation view factor program) has been compiled for MS Windows using the Lahey Fortran 95 (lf95) compiler,

• the Linux version of ShipIR/NTCS is now compiled using the following standard software components: Red Hat Enterprise Linux (v4), OpenMotif-2.2.3 and Mesa3D (v6.4.2),

• a new Interface from Maya Heat Transfer Ltd (www.mayahtt.com) allows the direct transfer of geometry and temperature files from the Maya software (TMG/FEMAP) to ShipIR/NTCS,

• the CSV output of ground and target in-band/thermal irradiation has been updated to output the new data associated with various options in the new directional irradiance module,
