Overview

WSF_OPTICAL_SIGNATURE provides the standard implementation used by optical_signature if the user did not specify a different implementation model. This model implements the signature as one or more sets of tables that apply when the platform is in a particular ‘state’. A ‘state’ represents a condition such as ‘bay-doors-open’.

The units for the dependent variable in the tables should be <area-units> (square meters).

<signature-name> is the name to be given to the signature. If the name specifies the name of an existing definition then the new definition will replace the current one (i.e. the last occurrence will be used for the simulation.)

Commands

interpolate_tables <boolean-value>

Specifies whether to apply interpolation to the defined Azimuth-Elevation Table Definition. The type of interpolation can be either linear or logarithmic (see interpolation_type).

Default true

interpolation_type <linear | logarithmic>

Specifies whether to use linear or logarithmic interpolation when interpolating data in the azimuth elevation tables.

Default linear

state [ <state-name> | default ]

Indicates that the following table definition will be used when the platform is in the signature state <state-name>. If default is specified then the subsequent table will be used if the platform is in a signature state that does not match any of the states defined in the signature.

If a state command is not specified, then the signature has one table that applies to all signature states.
