Simulation And Simulation Of The Radar Echo Signal

The radar signal simulation is mainly used to simulate the signal of the target and its condition, in order to get true reappearance of the radar signal. In the thesis, the video echo of the airborne PD radar was simulated. The simulated echoes include the signals of the target, the ground clutter and the noise.Firstly the thesis come up with wide uses of the radar simulator and reason, then the analysis of the target models, the clutter models and the spectral distribution of the ground clutter,and then the feasible method to simulate the radar echo which emphasises in the analysis and deducibility of simulation the ground clutter and, using grid-mapping format method. Secondly, the thesis offers simulations of the signal of the ground clutter and the video echo of the radar, the ground clutter's distribution is Ray Leigh, and its spectral is Gaussian, At last, as for a kind of airborne radar, the thesis gave the scheme about the digital signal processor of the radar signal simulator.
