Imaging Processor for Multi-Receiver SAS in the Presence of Partially Failed Receivers

Abstract:

For multi-receiver synthetic aperture image formation, if one or more receivers are failed because of unexpectable reasons, the synthetic virtual array may have to be pulled out from operation due to unacceptable pattern distortion. Here, a technique is presented for reconstructing the signals of failed receivers before synthetic aperture image formation. Its performance is validated by using simulated data, as well as real data collected by ChinSAS-150.
