Abstract

Abstract

Using "SZ-4" space-borne altimeter waveforms data on 7 to 8 February 2003,raw data are preprocessed,which include waveforms' 1 s average,thermal noise eliminatim and normalization.Then the trailing edge of the sea surface return wave waveforms is fitted with a fitting method to calculate the pointing angle of altimeter antenna.These results show that "SZ-4" space-borne altimeter pointing angle of altimeter antenna is almost wholly less than 0.024°,antenna pointing is very stable within computing time.
