Abstract :
In this work, the estimation of Doppler spectrum for simultaneous time varying conditions is analyzed. Based on the application of discretized radar cross section equations in a finite element approach, an in-house 3D code has been implemented in order to analyze the Doppler spectrum of objects with linear as well as rotation movement. Simulation results for the case of a helicopter with blade movement as well as rectilinear displacement are presented, where the combined effect on the resulting Doppler spectrum can be described.
