Abstract: This paper addresses an MIMO InSAR mode which integrates the multifrequency technique and multibaseline technique.More equivalent phase centers are obtained through the multiple-input and multiple-output technique,which would provide more independent interferometric data.Hence,a more reliable and accurate estimate of the terrain profile would be obtained.The performance of this MIMO InSAR mode is evaluated theoretically.The numerical analysis validates the superiority of the mode.
