Coherent interference tests for wind profilers

A coherent interference test for wind profilers is presented. The test determines whether or not coherent interference or "changing" coherent interference is small enough to have negligible effect on profiler wind estimates. The test is based on velocity estimates made when the profiler received signal is white, Gaussian noise. These mean radial velocity estimates are uniform over the Nyquist interval, and their distribution can be tested using the chi square test of goodness-of-fit for random variables. Methods for short- and long-term tests are described. The long-term test is for uniformity of distribution in time while the short-term test is across different range gates.
