Reliability of velocity measurement by MTD radar

For an ATC radar with moving target detector-type signal processing, admissible pulse recurrence frequency stagger ratios for expanding the unambiguous velocity interval are derived, and formulas and curves for the parameters describing the reliability of velocity information, based on simulation, are presented. In a noise-only environment, and for a Swerling 1 target with S/N resulting in P(d) = 90 percent, there is a probability of more than 50 percent of obtaining velocity information with an expanded unambiguous velocity interval of 832 knots and a standard deviation of less than 1 knot. The probability of false measurement is less than 0.00001.
