Your question is Radar and Mission Systems Basics. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me what you know about radar, how energy disperses, and mission systems, and give an example of what mission systems might be on a BBC news helicopter, an ice cream truck, and military vehicles.
