Actually I believe it zeros in on the locations of sources of emissions of interest, and pinpoints the grid location of said emissions, to be transmitted to the air-to-ground missiles or attack drones as target locations.
Also, I don't see the sources of drag you speak of. This is definitely a 300 mph or under drone (likely loiters at 100 mph or less), and seems quite slick to me. I see the shackles and the screws, neither of which are sources of high drag at likely mission speeds. The air intake for the engine is required, and turning it into a NACA duct would be a pointless expense that would gain but little for the money. The prototype's landing gear is already gone.
