What is range compression in SAR?

Range Compression / Azimuth Prefilter

As the radar travels along the flight track, the transmitted pulses are linear FM modulated chirp signals with a large time-bandwidth product. Range compression applies a matched filter in range to the recorded data as illustrated in Figure 1.

What does SAR mean in oil?

The main systems to monitor sea-based oil pollution are the use of airplanes and satellites equipped with Synthetic Aperture Radar (SAR). SAR is an active microwave sensor, which captures two dimensional images. The brightness of the captured image is a reflection of the properties of the target-surface.

What is SAR in signal processing?

Synthetic aperture radar (SAR) refers to a technique for producing fine-resolution images from a resolution-limited radar system. It requires that the radar be moving in a straight line, either on an airplane or, as in the case of NISAR, orbiting in space.

What is RAR and SAR?

There are two types of imaging radar apertures: real (usually called RAR or SLAR for side-looking airborne radar or SLR for side-looking radar) and synthetic aperture radar (SAR). The SLAR imaging system uses a long antenna mounted on a platform. The synthetic aperture is used in space remote sensing applications.
