Down-Looking Airborne Radar Imaging Performance: The Multi-Line and Multi-Frequency

The paper proposes an analytical study regarding airborne radar imaging performances and accounts for a down-looking system moving along parallel lines far, in terms of probing wavelength, from the investigated domain collecting multi-frequency multi-monostatic data. problem is formulated constant depth plane by exploiting Born approximation. Hence, linear inverse scattering faced considering both Adjoint Truncated Singular Value Decomposition reconstruction schemes. Analytical simulated results are provided to state how achievable depend on measurement configuration. These practical usefulness because, operative conditions, it unfeasible plan flight grid made up high number closely (in wavelength) spaced lines. understanding availability under-sampled data affects allows trade-off between collection constrains reliable reconstructions scenario under test.
