Abstract:
TASAT simulations of an approximate model of NASA Image Satellite have been conducted and the resulting time domain data of the passive cross section was collected. FFT of this data shows a clear significant peak at the frequency corresponding to the spin rate of the satellite. The spin rate of the satellite has been varied in the simulations and the corresponding change in the frequency location of peak has been correctly recovered. However, there are other significant peaks at carious low frequencies, caused by high reflectivity glint like objects on the surface of the satellite, cross talk due to interference of the glints and the mixing of the time returns from various parts of the satellite.
