The area of Moscow during the war was about 500 km2, with a population of over 4 million people.
For each departure to Moscow, the Luftwaffe lost about 10% of the aircraft (according to the Soviet data).
The first and the largest departure: 127 of 222 aircraft reached the goal (lost 22 aircraft), they dropped 104 tons of high explosive and 46 000 incendiary bombs - a total of 130 killed, 660 injured, destroyed 37 buildings. The German air raids continued until July 16, 1942 - total 2000 killed, 6000 wounded, about 5600 destroyed or damaged buildings.
London losses were higher - if I'm not mistaken? More than 600 fighters of the air defense (20% flew at night) and more than 1,000 barrels of guns is a good jamming.

I also found information about "radar jamming". In 1942 on aircrafts "ADD" appeared detectors radar beam. In 1943, the aircrafts "ADD" used passive jamming (metal tape). Soviet aircraft used radio direction finding. Also in the Soviet army actively used "radio jamming" against the Germans. The radar on the Eastern front, the Germans used a little. Question "radar jamming" became more important when the Soviet army came to Germany (late 1944-1945).
