The related clutter baseband signal generation method for satellite-carried bistatic radar comprises: setting initial condition, building the clutter equidistance ring model; deciding the clutter unit validation, calculating the clutter unit motion vector led by earth rotation; then, according to satellite position and orbit parameters, calculating satellite velocity vector and the corresponding time frequency and space frequency for clutter unit; summarizing all clutter unit space-time 2D fast-beat to calculate clutter covariance matrix and clutter data for succeeding algorithm processing. |
