Holographic synthetic aperture radar tomography (HoloSAR) combines circular (CSAR) and SAR (TomoSAR) to enable a 360° azimuth observation of the considered scene. This imaging mode achieves high-resolution three-dimensional (3-D) reconstruction across full 360°. To capture deformation information observed target, this paper first explores differential HoloSAR mode, which technologies CSAR TomoS...

Severe phenomena of across range-Doppler unit (ARDU) and decoherence occur when radar detects high-speed high-maneuvering targets, causing degradation in detection performance traditional FFT methods. The improvement resolution causes a multi-dimensional spread phenomenon, where different scattering centers the target are distributed on range units, along with motion parameters such as velocity...

In this paper, we consider the problem of testing two separate families of hypotheses via a generalization of the sequential probability ratio test. In particular, the generalized likelihood ratio statistic is considered and the stopping rule is the first boundary crossing of the generalized likelihood ratio statistic. We show that this sequential test is asymptotically optimal in the sense tha...
