What is SAR?

 

Radar Imaging Technology

Synthetic Aperture Radar (SAR) is a form of radar imaging that is used to create two or three dimensional images. Similar to a camera flash, SAR actively illuminates a scene and can generate images through clouds, smoke, fog and in total darkness.

 

At any given time, 70% of the Earth is covered by clouds and half is in darkness. This limitation results in 85% of Earth being largely undetectable to optical satellites.

Worldwide Coverage. Independent of Weather or Nightfall.

“The most obvious SAR advantage is the weather and daylight independence of radar systems, which ensures a guaranteed acquisition of the area of interest.”

What We Built

 

A Quantum Leap in Image Quality

We built a fully software defined radar utilizing the latest commercial technology to deliver exquisite image quality.  Combined with a powerful antenna and digital signal processing, the radar exploits more than 1,200 MHz of bandwidth to deliver 0.25 x 0.10 m imagery.

 

Our unique approach balances mass, volume and power while conforming to a microsatellite form factor.  This means higher quality images at a lower price point for your SAR data services and analytics. 

 

Contact us for detailed information about our spacecraft, payload and image processing algorithms.

What the Industry is Saying:

“[1,200 MHz bandwidth]…a quantum leap in image quality. The improved resolution facilitates the more intuitive analysis of the imagery as even small scaled objects are recognizable and identifiable easily.”

Compact and Lightweight

 

Rideshare Launch Compatible at Competitive Prices

Our microsatellites are compact and lightweight. Perfect for rideshare compatibility with an EELV Secondary Payload Adapter (ESPA) ring for affordable access to space. Launch ridesharing keeps our mission costs low, allowing us to pass savings on to our customers.

How Does it Work?

 

Balance Power & Aperture Area

Spatial resolution in SAR imagery may be improved in two ways. Range resolution (across-track) is improved by increasing the modulated bandwidth of the transmitted signal. Azimuth resolution (along-track) is a function of synthetic aperture size. We can achieve azimuth and range resolutions 0.25 x 0.10 meters by staring at a target while traversing the necessary synthetic aperture distance and generating a wide bandwidth waveform with a sufficiently powerful antenna.
