As far as I know Soviet radar was a non-entity until after the war. The Fronts moved along pretty quickly towards Germany from Kursk and production realities and the sheer size of the combined Soviet air armies actually meant the majority of aircraft flying over the Reich were built in 1943, just after the major types had been sorted out, let alone featured new technologies. They also concentrated on a strategic air arm once again only after the cessation of hostilities.

I do know they implemented a system of radio navigation stations from late-42 probably as part of the reorganisation of their air arms. But I think that's about as far as it went.

For an example of Soviet wartime technologies, the typical communications doctrine for artillery and armoured regiments in 1941 was to pull up at a civilian telegraph station and use that. Most of course were severed by the initial German artillery bombardment across the continent.
Then when reconnaissance and spotter planes were sent, of course they never returned. This was one of the factors which contributed to the dramatic German superiority of the battlefield in those early stages, and the tremendous victory scores of Luftwaffe pilots. Nearly a third of front line units were equipped with spanking new MiGs, but neither did the Soviets know how to pilot them, nor did they have any idea just what was coming.
