Abstract :
A modified distributed orthogonal matching pursuit algorithm is presented for sparse scene reconstruction in through-the-wall radar imaging applications. A distributed network of radar systems, each equipped with a single transmitter and an array of receivers, is considered. Ray-tracing based numerical simulation results are provided which demonstrate the effectiveness of the proposed algorithm.
