Utility FFT Codes: ftx.m fty.m fty.m ifty.m These four codes are forward and inverse FFT routines for a two-dimensional signal, e.g., f(x,y) and its Fourier transform F(k_x,k_y): x or k_x: first variable; y or k_y: second variable. The routines can be used for any two-dimensional signal, e.g., s(t,u). In this case, t is the first variable, and u is the second variable. For two-dimensional FFT, use ftx(fty(array). 2. Chapter 1 Code: range.m This code is for simulation and reconstruction in a one-dimensional range imaging system with a pulsed chirp signal. 3. Chapter 2 Code: crange.m This code is for simulation and reconstruction in a one-dimensional cross-range imaging system. 4. Chapter 3 Code: rad_pat.m This code provides the transmit/receive radiation patterns of a planar or parabolic radar, and their Fourier (Doppler) spectra. 5. Chapter 5 Code: spotlight.m This code simulates a spotlight SAR database. Four reconstruction algorithms (spatial frequency domain interpolation, range stacking, time domain correlation, and backprojection) are provided. 6. Chapter 6 Code: stripmap.m This code simulates a stripmap SAR database. Four reconstruction algorithms (spatial frequency domain interpolation, range stacking, time domain correlation, and backprojection) are provided. NOTE: The spotlight SAR and stripmap SAR codes were designed to have common features in their reconstruction section; this was done to create a common basis for the two SAR systems that was more comprehendable to the user. The user should customize and optimize these codes depending on his application; see the discussion on the MATLAB codes at the end of Chapters 5 and 6. For instance, one should incorporate the more restrictive support band of the target spectrum in the (k_x,k_y) domain that depends on the modality of the SAR system (i.e., spotlight or stripmap). Also, for the "wide-bandwidth" SAR systems, convert the "narrow-bandwidth" digital spotlighting (via polar format reconstruction) into its wide-bandwidth version. 7. Chapter 8 Codes: sig_sub_a.m sig_sub_b.m The first code, sig_sub_a.m, performs block-based signal subspace processing for detecting change or target registration using a simulated database. The second code, sig_sub_b.m, performs overlapping block-based signal subspace processing for motion tracking using a simulated database.
