FORWARD-LOOKING ANGULAR SUPER-RESOLUTION FOR MOVING RADAR PLATFORM WITH COMPLEX DECONVOLUTION

The conventional deconvolution approaches which just rely on amplitude information behave worse when the radar platform speed is fast, and the approaches which just use the doppler phase caused by the platform moving can't achieve forward-looking imaging. To achieve forward-looking angular super-resolution for moving radar platform, in this paper, a complex deconvolution method which utilizes both amplitude and doppler phase information is proposed. The complex convolution matrix is constructed through the corresponding relation between the amplitude and doppler phase. The truncated singular value decomposition (TSVD) method is applied to suppress noise amplification to achieve deconvolution. Simulations demonstrate that the proposed method can achieve forward-looking angular super-resolution for moving radar platform.
