**Analysis of Results**

Overall result of test cases given by a graph of the %error of the range approximation compared to "radar" from "Computer-Based Exerciese for Signal Processing Using MATLAB" by Burrus [ et al.] (see pages 328-329 for definition of parameters and function)

**Method of Error Calculation**

The % error was calculated by first taking the returned value for range from our developed program and using that as an input to the "radar" function from Burrus [ et al.]. The resulting waveform generated is then put through the same match filter as our simulated received wave. A comparison of the location of the 1st peaks is then done and the absolute value of the difference is taken. The value is then divided by the difference from the right most edge of "radar" 's first chirp to the end of the signal.

**Comment on % Error**

The % error increased in a direct proportional to however larger we made the new TD value. Thus, if a shift of TD=900 was applied, the % error was 9 times greater than in test case 5 ( TD = 100), it was in fact about 55.89%.

**Where to Next**

Next, look at "RADAR:Velocity Analysis" as next step.
