A sparse reconstruction algorithm for mainlobe towed jamming suppression [PDF]
SCIENTIA SINICA Informationis, 2019 A sparse reconstruction algorithm for near-mainlobe jamming suppression is proposed in this paper, which can suppress the mainlobe towed jamming (MTJ) effectively and extract the distance and direction of the target. Firstly, the orthogonal matching pursuit (OMP) algorithm is adopted to estimate the MTJ information containing direction, amplitude and ...
