Abstract :
The influences of the motion measurement errors (MMEs) to the 3D SAR imaging are analyzed based on the "one-active" LASAR system in this paper. Firstly, the principle and the spatial ambiguity function (AF) of the "one-active" LASAR are introduced. Then the 3D MMEs are introduced according to three forms: the 3D velocity errors and the 3D acceleration errors, the sine vibration errors and the array vibration errors. The 3D SAR system\´s maximum allowable MMEs are obtained and the influences of the 3D MMEs to the 3D AF are analyzed by the numerical simulation. Finally, the ground experiments and its results are presented, which validate the feasibility of the "one-active" LASAR.
