Radar detection and tracking of German V-2 rocket launches in WW21

For CH, while no useful warning to Londoners could be achieved, the important function of trajectory backtracking to identify V-2 launch points could be made, aiding site attack planning. For the See-Elefant, it could possibly measure V-2 impact points on London, which would aid assessment of V-2 in-flight performance. The former technique is used today by counterbattery radars and the latter by range instrumentation radars.
