Reconstructed Target Range Profile via Unitary ESPRIT Superresolution Algorithm
International Journal of Antennas and Propagation, 2017 We propose an efficient technique for target classification using one-dimensional high resolution range profile (HRRP). The proposed technique utilizes the unitary estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm to
