A UAV-Friendly Strategy for Moving Targets Processing Using SAR
Abstract
This paper presents a novel technique to estimate all the trajectory parameters of fast moving targets using a single SAR sensor without increasing the PRF. The basic reasoning is that, although the returned echoes may be aliased in the azimuth direction, their phase and amplitude are informative with respect to the moving target trajectory parameters. The proposed method samples the data in the spatial domain and extracts the data along the signature curve that depends of the moving target trajectory parameters. The resulting algorithm is a highly efficient (from the computational point of view) 1D matched filter. The effectiveness of the proposed algorithm is illustrated with simulated and real data.
