# A generic SAR sensor
|
|
#
|
|
# The user of this definition is responsible for setting the installation
|
|
# location and orientation using the 'location', 'yaw' and 'pitch' commands
|
|
# in the instantiation of the sensor on the platform(_type).
|
|
#
|
|
# This implementation supports both spot and strip modes in a high and low
|
|
# resolution.
|
|
#
|
|
# mode resolution
|
|
# ------------- ----------
|
|
# SPOT_HI_RES 1 m (default mode)
|
|
# SPOT_LO_RES 5 m
|
|
# STRIP_HI_RES 1 m
|
|
# STRIP_LO_RES 5 m
|
|
#
|
|
# The default implementation does not automatically turn off for spot mode.
|
|
# If the user desires this capability, they should specify

# sensor sar GENERIC_SAR
