To summarize, the qualities that make radar essential to modern life also limit its utility. The fact that it furnishes its own illumination makes it valuable for obtaining almost instantaneous range and range rate data on targets and for night operations against passive or noncooperative targets, but this limits its ultimate range. The fact that the frequencies at which radars operate can penetrate bad weather, smoke, and dust and can see over the Earth's horizon makes them essential to emergency operations, particularly military operations, but prevents them from obtaining the high resolution they need to get fine-grained images. The vigorous application of new technology and human ingenuity will tend to expand radar's applications and mitigate its shortcomings. However, the natural laws cannot be overcome, inevitably consigning radar to its niche: an interesting and important technology with multifaceted but limited uses.
