WebLong Coherent Integration in Passive Radar Systems Using Super-Resolution Sparse Bayesian Learning Abstract: Maximizing the coherent processing interval (CPI) is crucial when performing passive radar detection on weak signal reflections. In practice, however, the CPI is limited by the target movement.
