Synthetic aperture radar (SAR) is a technique to synthesize a long antenna, utilizing the movement of the sensor using signal processing at ground to produce better azimuth resolution for larger swath imaging. SAR system design is an iterative process. It involves the derivation of system parameters from the user requirements and takes orbital geometry and practical system realization feedback into the loop. For the system design, we developed software in MATLAB® using Phased Array System Toolbox™ and Antenna Toolbox™.

During the development of SAR payloads, we focused on developing automated checkout systems to process and validate the payload data. Our goal was to reduce processing and validation time and have minimum human interference. We also developed an automated error report generation software to process and validate SAR payload data using MATLAB, Symbolic Math Toolbox™, Signal Processing Toolbox™, and MATLAB Report Generator™. We found that the software was user friendly and achieved the automation objective quickly.
