What is SAR 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 signal processing algorithm?

Digital signal processing algorithms are typically built up from three basic functions: Add, Multiply, and Delay. The functions are applied in combination to build up complex algorithms in discrete time systems. The Multiply and Add functions are known as operations or ops.

Is SAR the same as LiDAR?

LiDAR requires an aircraft flight making it a costly option and weather dependent. SAR technology is acquired through an orbiting satellite that is more cost effective and can penetrate through cloud coverage. Both are able to acquire images during day or night.

What is SAR data processing and its applications?

Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars.
