A S ynthetic A perture R adar SARor SAR, is a coherent mostly airborne or spaceborne sidelooking radar system which utilizes the flight path of the platform to simulate an extremely large antenna or aperture electronically, and that generates high-resolution remote sensing imagery. The signal processing uses magnitude and phase of the received signals over successive pulses from elements of a synthetic aperture.
After a given number of cycles, the stored data is recombined taking into account the Doppler effects inherent in the different transmitter to target geometry in each succeeding cycle to create a high-resolution image of the terrain being over flown. The SAR works similar of a phased arraybut contrary of a large number of the parallel antenna elements of a phased array, SAR uses one antenna in time-multiplex.
The different geometric positions of the antenna elements are result of the moving platform now. The SAR-processor stores all the radar returned signals, as amplitudes and phases, for the time period T from position A to D.
As the line of sight direction changes along the radar platform trajectory, a synthetic aperture is produced by signal processing that has the effect of lengthening the antenna. As a target like a ship first enters the radar beam, the backscattered echoes from each transmitted pulse begin to be recorded. As the platform continues to move forward, all echoes from the target for each pulse are recorded during the entire spotlight ssynthetic aperture radar pdf download that the target is within the beam.
The point at which the target leaves the view of the radar beam some time later, determines the length of the simulated or synthesized antenna. The synthesized expanding beamwidth, combined with the increased time a target is within the beam as ground range increases, balance each other, such that the resolution remains constant across the entire swath. The achievable azimuth resolution of a SAR is approximately equal to one-half the length of the actual real antenna and does not depend on platform altitude distance.
SAR radar is partnered by what is termed Inverse SAR abbreviated to ISAR technology which in the broadest terms, utilizes the movement of the target rather than the emitter to create the synthetic aperture. ISAR radars have a significant role aboard maritime patrol aircraft to provide them with radar image of sufficient quality to allow it to be used for target recognition purposes. The slant-range distortion occurs because the radar is measuring the distance to features in slant-range rather than the true horizontal distance along the ground, spotlight ssynthetic aperture radar pdf download.
This results in a varying image scale, moving from near to far spotlight ssynthetic aperture radar pdf download. Figure 4: Foreshortening. Figure 5: Layover, spotlight ssynthetic aperture radar pdf download. Figure 6: Shadowing. Figure 2: The synthesized expanding beamwidth.
