The peak method currently used for the phase measurement of a point target signal, which takes the phase of the peak reflector response as the signal phase estimate, is analyzed and shown to be sensitive to focus. A novel method based on the integration of complex data is proposed for the extraction of signal parameters of a point target in the presence of clutter. This method, called the complex integration method, is shown to be nearly insensitive in both phase and magnitude to processor focus
