Research on Simplified Model of Spaceborne Early-warning Radar Clutter Simulation

In order to simulate the spaceborne early-warning radar echo, a clutter simulation model is proposed. In spaceborne radar clutter simulation, the problem of two-dimensional widening in the range-Doppler domain of traditional simplified model is analyzed, as a result of beyond the precondition of the conventional airborne clutter simulation model. For the spaceborne condition, a new simplification is proposed. Taking into account the accuracy and efficiency of the simulation, a simplified spaceborne warning radar clutter model is proposed. The simulation results show that the new model improves the accuracy of the clutter simulation compared with the traditional one, and the simulation efficiency is taken into account as well.
