A Fast Simulation Method in Range-Doppler Domain for Airborne Radar Clutter

The technology of clutter simulation is essential in radar design and electromagnetic environmental effects analysis. To meet the requirement for real-time simulation, a fast clutter simulation method for airborne radar is proposed in this paper. By simplifying the clutter model in range-Doppler domain, the dimension of the clutter simulation data is reduced. And a fast simulation method in range-Doppler domain is proposed. Compared with the traditional method, the computational complexity of the RD(Range-Doppler) method proposed in this paper is significantly decreased. The simulation results show that the RD method proposed in this paper has improved efficiency while ensuring simulation accuracy.
