Abstract :
ldquoOne-activerdquo LASAR is a kind of linear array 3-D image SAR system that only one element of the linear array is active at every footprint. This paper will analyze three major system errors presented in the ldquoone-activerdquo LASAR experiment, which is startup synchronization error, PRF error and obliquity error, and introduce a method to correct them. The analysis and correction are supported and proved by experiment results.
