Abstract

A novel ground-based bistatic polarimetric synthetic aperture radar (SAR) system using an Optical Electric Field Sensor (OEFS) as the receiver was developed for environmental studies. Fundamental experiments were carried out with a trihedral corner reflector (CR) as a target, showing the polarimetric capability of the system. Different polarization signatures from the monostatic SAR images were found by analyzing the bistatic polarimetric SAR images. Meanwhile, this system has the capability to estimate the two-dimensional (2D) displacement of the targets in the field of view. The simulation shows the feasibility and effectiveness of the 2D displacement estimation. The experimental results demonstrate that the accuracy along the x and y direction to the line of sight (LOS) based on the designed bistatic synthetic aperture radar system can reach millimeter level for the displaceable corner reflector.
