Summary

Description
English: Members of the 58th Searchlight Battery work on the SLC Mark VI radar on the 150 cm searchlight. The radar worked by sending a signal out of the antenna at the very top (being held) and received on the four antennas below it. By delaying the signals from the four receivers, the sensitive direction of the array as a whole could be directed off-center and then rotated. By watching the return signals as the beam rotated, the direction of the target could be determined. The Mark VI refers to the mounting, not the radar itself, which had several other Marks depending on what it was attached to.
