摘要：

This correspondence derives the Cramer-Rao lower bound for the variances of the estimated parameters of complex signals with constant amplitude and polynomial phase, measured in additive Gaussian noise. Signals of this type appear in many radar applications, and the CRLB formulas have practical importance in these applications. Exact and approximate forms of bound are presented. The approximation error is of second order in the number of measurements.
