An Airborne SMAP Simulator for Australia

• PLMR radiometer PLIS radar on same aircraft
• PLMR
• 1.4GHz radiometer
• V H
• 6 beams (7º, 21.5º, 38.5º)
• 1km res. (from 3km alt.)
• PLIS
• 1.26GHz radar
• fully focused SAR
• InSAR capabilities
• V H on transmit and receive
• 10m res. (from 3km alt.)

The system will allow collection of data which
are a scaled replicate of SMAP acquisition in
terms of incidence angles, swath coverage and
resolution ratio between active and passive data.
