Hi, I'm getting the same output as above on my CRO after the frequency fixer. But I think so I'm supposed to get a DC signal. I'm I going in the right direction towards building my RADAR? P.S. I'm using dipole & yagi antennas.Please reply.
Your antennas are obviously different (at the very least, nicer aesthetically) than the ones that MIT used since they're not coffee cans. Do they work just as well and how did you make them if you don't mind sharing? Thanks!
Hi, No problem. Those patched antenna pairs I purchased at ebay for 7 USD per unit. If you pass me your mail I can add you the test results of the CAntennas and those patched Antenna I did in an Antenna an echoic chamber. The patched Antenna are quite narrowband, check in the net for "High gain 2.4GHz 14dBi directional..." , but I think the seller removed them from ebay. Good luck for your project.

pedro.gnzlz.flrs@gmail.com my english is very bad... zorry, but arduino calculate fft and labview display or labview calculate fft and arduino send data. i can't synchronous serial communication for arduino. thanks.
