Publikováno v: Tongxin xuebao, Pp 13-18 (2008)

A new direction finding algorithm called conjugate propagator method （COP） for one-dimension signals was proposed. The new algorithm uses the array output and its conjugate form to extend the array aperture so that it can detect more signals than

Located at Dome A, the highest point of the Antarctic plateau, the Chinese Kunlun station is considered to be one of the best ground-based photometric sites because of its extremely cold, dry, and stable atmosphere(Saunders et al. 2009). A target can

International audience; From the experiences learned in three decades of exoplanet search, wide-field transit surveys have proven to be one of the most effective ways to detect exoplanets. Wide field of view, however, suffers from high false-positive

Planetary systems can survive the stellar evolution, as evidenced by the atmospheric metal pollution and dusty disks of single white dwarfs. Recent observations show that 1 to 4 percent of single white dwarfs are accompanied by dusty disks, while the

Focusing transform-based direction-of-arrival method exploiting multi-cycle frequencies

Autor: Hung Zhitao, Jiang Wenli, Zhou Yi-yu

Publikováno v: Progress in Natural Science. 15:491-495

When single cycle frequency is employed, the existing spectral correlation-signal subspace fitting (SC-SSF) algorithms usually contain two disadvantages: those single-cycle estimators cannot reach the best performance: it is inconvenient to be applie
