LOFAR test station data
- The LOFAR test station data were recorded using 25 frequency bands of 156kHz using 45 antennas
- Dirty images (MVDR) were calculated for the original data
- Data were corrupted by a terrestrial source with intensity of 106(a milion)
- Standard approach yield a corrputed image
- ASSC dirty images are unaffected by the terrestrial source

- Standard approaches fails
- dirty image is corrupted to a level where no image enhancement
algorithm can recover the true sources from the strong interfering
source
- ASSC algorithm is immune
- obtains images that show the true sources, eliminating the corruption
due to the terrestrial source
