| Abstract: | Based on the previous results on the spatial correlation characteristics of some typical land clutter, and in accordance with the specialty of pseudo random code CW (PRC -CW) radar, i.e., the time spread of echo signal under the condition of low grazing angle, a superposition algorithm was used to get real clutter echo of PRC -CW radar. The correlation characteristics of land clutter for PRC -CW radar was investigated with simulation method. |
