Yes, i know this. I talked about that in the past. When I mentioned Burfis in the past, I wrote the exact same thing (360 degree radar coverage), but now I have this info that is different than the past info.
Data-link, sensor fusion, IRST, wide-angle AESA radars like Raven, passive sensors, cheek arrays. There are multiple solutions. Of course, having cheek arrays as a brute force solution is good, but cheek arrays don't have the same capability as the nose array. Nose array is bigger, have more power output, and range.
