There were a total of 3 SAR imaging systems developed for this dissertation.  The first is an S-band linear rail SAR which is capable of imaging targets in free space and behind lossy dielectric slabs at stand-off ranges.  This system is a linear FM chirped radar, 2-4 GHz, using 10 milli-watts of transmit power, sensitivity of better than -125 dBm.  All hardware was developed in my basement laboratory/garage machine shop.
