Signal Processing in FMCW Radar - Range, Velocity and Direction

In his book Multirate Signal Processing, Fred Harris mentions a great problem solving technique: "When faced with an unsolvable problem, change it into one you can solve, and solve that one instead." In this video, you will find how an FMCW radar is one of the most beautiful applications of this approach. - The apparently logical method to measure the range of an object is through estimating the time delay of a reflected wave (on the order of a few nanoseconds) that is both expensive and less accurate. We can associate the range with the frequency of a sinusoid and measure that instead. This proves to be much simpler and accurate. - There is another surprising way to apply this idea here that can only be understood after delving into the details.
