Abstract
For reducing speckle in echo signals derived from reflections of pulsed coherent waves, the echo signals are subjected to amplitude and phase/frequency demodulation and the resultant amplitude and phase/frequency data are multiplied to generate an image signal. Selective control of the multiplication process may be provided in accordance with signal amplitude and/or signal-to-noise ratio.
