Martti T. Hallikainen received his Ph.D. in 1980 from the Helsinki University of Technology (HUT) on UHF and microwave radiometry of sea ice. Since 1987, he is professor of space technology and director of Laboratory of Space Technology at HUT. His main area of research is microwave remote sensing, including construction of microwave radiometers and radars and development of algorithms to retrieve characteristics of geophysical media from satellite and airborne microwave data.

He lead the development of the airborne 14-channel (6.8 to 94 GHz) microwave radiometer HUTRAD, accommodated onboard the HUT research aircraft Skyvan, and he is presently in charge of the construction of the HUT airborne 1.4 GHz two-dimensional synthetic aperture radiometer. The 1.4 GHz radiometer employs both a centralised and decentralised calibration system. His expertise in algorithm development includes the use of SMMR and SSM/I data for retrieval of sea ice concentration, snow water equivalent, and boreal forest characteristics. He has been the Principal Investigator in several ESA and EU funded projects related to microwave radiometry.

Role in the SMOS mission:

Martti Hallikainen will coordinate the development of geophysical retrieval algorithms for cryosphere (sea ice, land ice, snow). He will also participate in airborne campaigns with the HUT 1.4 GHz synthetic aperture radiometer to support algorithm development and validation for various targets and development of the SMOS calibration concept.
