7.7.3. Fine Doppler Estimator

The fine Doppler estimator design example is an interpolator for radar applications. The example has three complex input values. It calculates the magnitude of each value, then performs a parabolic curve fit, identifies the location of the peak, and calculates the peak magnitude. The example performs all processing in single-precision floating-point data.

For more information about fine Doppler estimators, refer to Fundamentals of Radar Signal Processing by Mark A. Richards, McGraw-Hill, ISBN 0-07-144474-2, ch. 5.3.4.
