Autofocus technique for radar coincidence imaging with model error via iterative maximum a posteriori

Autofocus technique for radar coincidence imaging with model error via iterative maximum a posteriori

Radar coincidence imaging (RCI) is a recently developed staring imaging technique based on the wavefront random modulation and temporal–spatial stochastic radiation field. Before coincidence imaging processing, the RCI needs to compute the reference matrix accurately. Unfortunately, model error usua...
