Real-Time Unfocused SAR Processor For Airborne Maritime Patrol Radar
ABSTRACT The modern airborne patrol radar benefits from having a real-time SAR capability. The high-resolution coast-line imaging, and vessel identification in maritime patrol radars can be done effectively in SAR mode. Telecommunication Research Institute in cooperation with Warsaw University of Technology started in 2003 project of an onboard SAR imaging processor for maritime airborne patrol radar. Such a processor has been introduced into a new version of Polish airborne radar and has been successfully tested by Polish Navy and Polish Coast Guard.

ABSTRACT: Recent research on synthetic aperture radars (SARs) in Poland is presented. The research started in 2002 and resulted in the first focused SAR image being obtained in the following year. The Telecommunication Research Institute and the Warsaw University of Technology have carried out the trials in order to work out efficient algorithms for radar imaging in different radar modes. The experiment consisted of two main stages. During the first stage, different SAR algorithms were tested using simulated data generated by a raw radar data simulator. During the second stage, real-life data were collected during the flight of an aircraft using a modified non-coherent radar. The collected data were processed offline. During the experiment, three techniques were tested: Doppler beam sharpening, unfocused SAR and focused SAR. The experiment was accomplished successfully and the obtained results allowed the start of research into the real-time implementation of imaging algorithms.IEE Proceedings - Radar Sonar and Navigation 05/2006; · 0.55 Impact Factor
