A Study on Early-warning Radar Signal Simulation

The correlated video signal of airborne early warning radar is studied in this paper. Radar signal radiation, propagation and scattering, and its processing in the radar receiver are simulated. The RCS of scattering object is computed by using OpenGL software package and its dynamic characteristic is simulated with the Swerling model. The land clutters are simulated by using the backward mapping method and its functional dependence on the incident grazing angle etc. is also accounted for. The dynamic characteristics of land clutters and echo noise are simulated by using random numbers described by the normal distribution.
