Narrative:

The aircraft was cruising at FL390 when the radar went out. About 5 mins later the aircraft entered the top of a cumulonimbus, I then turned left to avoid it when both engines spooled down. The anti-ice was turned on. We declared an emergency with center, and descended to about 22000 ft and air- started both engines. Then advised ATC that everything was okay and continued another 50 mi or so to our destination. I feel the cause of both engines to fail at the same time was the failure of the radar and the pilots not able to see the top of the storm cell when we entered it. I believe that at an altitude of 39000 ft in a falcon 20 the turbulence was the cause of engine failure.
