For reference USN 300kw surface search of that time frame could see the hardware on a utility pole at 40 miles under ideal conditions. Rain reflections, sea surface clutter, and sweeping the right sector while riding the wave crest come into play.
Thanks. I know the Anderson had two types of radar. One worked at a distance, and the other was better for closer objects. For most of the afternoon/evening, they were about 10 miles behind the Fitz.
