What you know is that I chose to answer the question asked my way and correctly. LOL.... You can chose to infer from that whatever you wish. Not based upon the answer provided, but a bias of interpretation. 1. I know you do not publish in your own name. 2. You know I can point to examples of my work product. In your analysis of my reply which of the above are relevant to what I may know or not. I infer you are implying you can use differential equations using matlab... That's not bad for you anyway. But I was unaware that matlab or Ma... would show you the steps to solve that equation. What was the full question your asked. Is your suggestion of a solution a reliable way to gauge if I have knowledge of Matlab or Mathematica. My suggested solution gave the steps to fully answer the question you asked. Can't handle a simple ordinary answer LOL Is your problem ???? 1. reading comprehension. 2. Writing clearly 3. Thinking 4. some of all of the above. Is mathlab yet cost effective for the following. So a simple, question. to perform the math to solve the transformation of I/Q data and and three axis acceleration data for time correction.(phaseshift), to create this image. acute.ath.cx How much additional processing power is require using matlab vs using a dedicated program with the best commercial or gnu compiler and math libraies. acute.ath.cx see: InterFerometric Synthetic Aperture Radar (IFSAR) is basically a SAR with a second antenna. Very simply explained, use of a second antenna is similar to using binoculars versus a telescope, one can perceive depth by using both eyes rather than one. IFSAR is based on collecting imagery (echoes) from the same scene using two spatially separated points (antennas) from which an interferogram can be formed and used to determine height, hence the added name "interferometric" SAR. Through phase unwrapping (on a computer) of the return radar signal(s), two images can be resolved and used to differentiate height and subsequently build a 3-D map. acute.ath.cx This is the simple physics. The motion of a moving aircraft creating the synthectic apperture over several tens of seconds are linear equations. raw sar data. acute.ath.cx SAR. 1 channel of 4 acute.ath.cx IFSAR, 2 of 4 channels used. GMTI, 3 of 4 channels are used. f-111.net #reply-75391481 mirror of.
