| Abstract: | Methods for developing mathematic model and performing numerical simulation of radar clutter are discussed. A system of radar clutter simulator based on DDS is presented. This simulator was implemented by combined means of software and hardware, and can theyibly generate many kinds of radar clutter with different waveforms, including ground clutter, sea clutter, cloud-rain clutter and chaff clutter. |
