Matrix approach to modelling of SAR signals

The paper presents a matrix approach to implementation of SAR signal generating and processing schemes. This approach is advantageous when matrix oriented software such as Matlab is used. Algorithms written in this type of software packages run faster compared to the same algorithms written for the same package using classical programming techniques such as loops, for instance. The approach is used to implement a SAR signal simulator in the Matlab and Simulink packages. A technique based on the evaluation of a superposition integral in the Fourier domain is used. First results from the implementation of an algorithm presented in literature are shown and a modified technique is proposed to eliminate certain limitations found in the original algorithm.
