Abstract :
A new ranging algorithm for frequency modulated/continuous wave (FM/CW) radars is given. This algorithm is near optimal, very robust, does not depend on the type of modulation, and is fairly easy to compute. An example of an older algorithm based on sinusoidal frequency modulation (FM) used on the MK-95 CW radar is given to illustrate shortcomings in typical older algorithms and for comparison purposes. The characteristics of the new ranging algorithm and test results from the MK-95 radar are provided. The actual target range and the one calculated using the new ranging algorithm differed by less than 1%
