Stripmap SAR employs a linear collection geometry and a fixed antenna orientation, typically to broadside, that is, normal to the platform velocity vector. This mode of operation achieves the finest possible cross-range resolution while surveying the passing terrain without gaps in coverage. This chapter covers the following topics: review of radar imaging concepts; Doppler beam sharpening extension; range migration algorithm; range-Doppler algorithms; and operational considerations.
