Localisation And Imaging Methods for Moving Target Ghost Imaging Radar Based On Correlation Intensity Weighting
This addresses motion-induced imaging issues in ghost imaging radar, an incremental improvement for radar imaging applications.
The paper tackles the problem of target imaging deterioration in ghost imaging radar due to relative motion by proposing a correlation intensity weighted localization and tracking imaging method, which was verified in simulation to locate and image targets effectively.
Ghost imaging radar is a new system of gaze imaging radar with high detection sensitivity, super-resolution and better anti-interference performance, but the relative motion between the radar system and the target will make the target imaging deteriorate. This paper proposes to perform absolute position localisation of a single target in the field of view by weighting the correlation strength of a single frame image of rough target, and to compensate translation of the reference arm speckle according to the localisation and tracking trajectory to accumulate the rough image into a high quality image. The proposed correlation intensity weighted localization and tracking imaging method has been verified by simulation to be able to locate and image targets in the field of view well.
