GEMA was one company that pioneered this technology, while Klein Heidelberg parasitized off of another instance of this technology. A center for this technology was the target of Operation Biting, which Josef Kammhuber names an instance of. Henry Tizard led a committee that investigated (-5[1])the deployment (15[1]-5[2])of this technology, which was countered by “window.” (15[1])IFF (15[1])using this technology (15[1])was one proposed (15[1])feature of (*) Chain Home, the centerpiece (10[1])of the (10[1])Dowding System. (10[4])A (10[1])myth about carrots (10[2]-5[2])improving (10[1])vision (10[7]-5[3])may (10[1])have been (10[4])a (10[1])cover (10[9])for (10[2])this (10[1]-5[1])technology, (10[11])which (-5[1])was eventually used (10[1])to detect V-2s. Ground stations managed to detect many German fighters during the Battle of Britain with, for 10 points, what technology that uses radio (10[1])waves to search for targets? ■END■ (10[8])
