Airborne Bistatic SAR Imaging for Parallel translational variant Configuration

摘要：

The transmitter and receiver at the difference velocity along parallel trajectories constitutes the parallel translational variant configuration whose echoes have two-dimensional space variant properties. The paper proposes a full analytic imaging algorithm for this configuration in two-dimensional frequency domain. Considering the contribution difference in the Doppler modulation ratio between the transmitter and receiver, their Doppler contribution ratio is used as the weighting factors to derive two-dimensional frequency spectrum of the echo of a target. Utilizing the relations of a target relative to the transmitter and receiver tracks, the spectrum is expressed a uniform formula relative to the receiver track. After compensating the bistatic deformation term, the 2D-CZT is used to correct the residual migration in range and azimuth, thus the focused image is obtained. The simulations validated the 2D-CZT algorithm.
