SAR triangle CW LFM signal formation and imaging

Synthetic Aperture Radar (SAR) with triangle Linear Frequency Modulated (LFM) Continuous Wave (CW) is considered. Algorithms for signal formation and image reconstruction of a moving target are suggested. Three-dimensional (3-D) SAR geometry of the target presented as an assembly of point scatterers is analytically described. Mathematical expressions for distance vector determination defined from SAR to each point scatterer are derived. SAR signal model based on a triangle linear frequency modulated continuous wave emitted signal, 3-D geometry and reflectivity function of the target is derived. Image reconstruction procedure based on Fourier transform for range compression and azimuth compression is applied. SAR imaging algorithm of a moving target is suggested. Numerical experiment is carried out.
