Quantum Radar: Good Idea or Snake Oil?

We survey the latest theoretical results that quantify the benefits of quantum radar compared with optimal classical radars.  We survey all of the known real world experiments for quantum radar.  We analyze the cost of quantum radar compared with classical radars.  We explore the question of what quantum radar is good for in the real world.  We give an annotated list of a few good papers.  We discuss the recent Chinese quantum radar demonstrations.  We explain some of the practical limitations of quantum radar.  We speculate about future research in quantum radar.  This talk is for normal radar engineers (and others) who do not have quantum mechanics for breakfast.  No knowledge of quantum mechanics is required to understand this talk.
