What is SAR?

Synthetic Aperture Radar (SAR) is advanced imaging technology used to capture earth imagery and create 2D and 3D reconstructions of land and sea objects at any time and in any weather condition.  PredaSAR takes this technology to a higher level by integrating SAR on-board small satellites that continuously travel around the earth in low earth orbit to provide persistent global coverage.

One of the main advantages of the SAR technology is how it can synthetically produce higher resolution images in any weather conditions, day or night.

How does SAR work?

To create a SAR image, successive pulses of radio waves are transmitted to "illuminate" a target scene, and the echo of each pulse is received and recorded. The pulses are transmitted and the echoes received using a single beam-forming antenna, with wavelengths of a meter down to several millimeters. This process forms the synthetic antenna aperture and allows the creation of higher-resolution images than would otherwise be possible with a given physical antenna.

The antenna illuminates an area on the ground determined by its wavelength and antenna dimension.  Pulses are sent and received continuously such that any point on the ground is sampled numerous times to generate images.
