DIY Synthetic Aperture Radar

Posted by kdawson on from the be-the-first-on-your-block dept.

An anonymous reader lets us know about a DIY synthetic aperture radar built for $240 in parts (give or take). Here's PDF slideware from the Ph.D. student's research. "Using a discarded garage door opener, an old cordless drill, and a collection of surplus microwave parts, a high resolution X-band linear rail synthetic aperture radar (SAR) imaging system was developed for approximately $240 material cost. Entry into the field of radar cross section measurements or SAR algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments."

    "A National Instruments PCI-6014 data acquisition card triggers radar pulses and digitizes the video data". http://sine.ni.com/nips/cds/view/p/lang/en/nid/11442 With a $700 (not counting accessories) data acquisition card.

      $150 to $450 on EBay, but still your point is valid.

    You're right. I know the author of the slides. This was part of his PhD disertation. He graduated about 2-3 years ago. He just recently posted the "how to" on his blogspot page this week.
