In this paper, based on the processing results of measured clutter data in forward scattering radar, a special phenomenon
that the clutter spectrum spread is insensitive to the wind speed and carrier frequency is observed. The pendulum model is
first time introduced into the physical modeling and formation mechanism analysis of surface clutter, and the quantitative
expression of clutter spectrum spread is analytically obtained. Under the assumption of pendulum model, the processing results
of measured clutter data agree well with the results of theoretical analysis, which fully verifies the correctness of pendulum
model and reveals the formation mechanism of surface clutter spectrum in forward scattering radar. Furthermore, according
to the stability of clutter spectrum spread with respect to carrier frequencies and wind speed, the optimal cutoff frequencies
of clutter filter can be obtained, which establishes the basis for moving target detection and accurate parameters estimation. |
