Ramp response radar imaging: Analysis of frequency parameters

Low frequency imaging in radar domain can have applications for stealthy or buried targets. Transient scattering response from a ramp waveform is related to the profile function of the target, namely its transverse cross-sectional area along the line-of-sight, and it thus provides information about the target size, orientation and geometrical shape. Indeed, such profile functions can be used for generating a 3-dimensional image of the target shape. However the required frequency band is very large and may involve difficulties for experiments as well as simulations. That is why, we propose to study the effect of these frequency parameters on targets profile functions and, consequently, on their reconstructed shape.
