Echoes of War

This book presents a passionate first-hand account of the development of the Home Sweet Home (H2S) radar systems during World War II. It provides numerous personal insights into the scientific culture of wartime Britain and details the many personal sacrifices, setbacks, and eventual triumphs made by those actively involved. Sir Bernard Lovell led the group that developed the H2S radar system to identify towns and other targets at night or during heavy cloud cover. H2S was successful during the attack on Hamburg in January 1943 as well as the air war against U-boats in the Bay of Biscay.
