SetConstraint (Radar)

Set constraints for a radar system

Syntax

SetConstraint <RdrObjectPath> {ConstraintName} <Parameters>

Related Commands

Description

Caution should be exercised when turning a constraint Off, in that any previously set constraint values may be lost. These cannot be recovered when the constraint is subsequently turned On.

The SetConstraint command turns radar constraints On and Off and also sets values for the constraints. The following Tables list valid values for {ConstraintName} as well as the parameters accepted for each. Only one constraint can be set with each SetConstraint command. All angle, latitude and longitude input values are entered in degrees.

SAR Constraints

The SAR constraints will not be applied unless the SAR mode is enabled, see the Radar command to set the Model.Mode attribute to "SAR".

SAR Constraints are also available for GroundVehicle, Ship, Facility, Place and Target objects.
