British & German raids against each others radar sites

Reading about the Dieppe raid by the British in 1942. What if the Germans realized the British had taken German radar information/equipment as part of the raid? Realizing this, the Germans plan their own raid(s) on several British radar sites. If the Germans realized how effective the British radar was vs their own, would the Germans then start attacking British radar sites and what would of been the result of this if Germany attacked Britain with bombers again?
