Other AbstractSynthetic apertu rem icrow ave radiometer rep resents a new techno logy being developed fo r passive microw ave remo te sen sing. Apertu re syn thesis u ses in terferomet ric techn iques to overcome the lim itat ion s set by an tenna physical apertu re w h ile wo rk ing at low er f requency.Two of the key geophysical parameters are so ilmo istu re and ocean salin ity w h ich requ ire ob servat ions at long wavelength s and therefo re large an tennas.This techno logy p rovides a possible so lu t ion to balance the requ irement come f rom spatial resolution measu rement sen sitivity and an tenna size and weight.D iffer f rom the to tal pow er radiometer, Syn thet icapertu re m icrow ave radiometer measu res the coheren t products f rom pairs of an tennas as a funct ion of baselines and the target called visib ility of the b righ tness temperatu re. Befo re the in strument get ting in to practical app licat ion,calib rat ion mu st be done.It invo lves relat ing the ou tpu t indicat ion (visib ility) to the b righ tness temperatu re at the inpu t and imp roving the radiomet ric sen sit ivity.In th is paper, calib rat ion algo rithm s fo r a onedimen sional syn thet ic apertu re m icrow ave radiometer are p resen ted.A f ter individually analyzing the th inned an tenna array calib rat ion and mu lt ip lechannel receiver calib rat ion,it also presents the image recon st ruction formula of the in strument.
