Conclusions

• Current SAS systems now have all the attributes
  first proposed in the mid 1070s by SAR engineers
• Although with all the limitations of a coherent
  imaging system, SAS side-scan images are
  approaching optical quality
• Apologies to anyone who though they should be in
  this collection
