[Laser] EME Experiment

[kd7ts]

Hi Tim,

Sounds like a great experiment. I understand long term integration using RF. This simply uses the difference of non coherent noise and coherent signal to average the noise and signal over time

In the case of the light pulse, it seems to me, the frequency is not the interesting data, but rather the timing. If this is true, I have serious reservations concerning the softwares ability to provide the desired performance. I have no successful experience with timing to this level of accuracy, but I do know that X86 based processors and the PC clock are pretty poor performers concerning time.  Wolf provides some "work arounds" in the Spectrum Lab program, but I am not sure this is what's needed. 

I followed your link(s) but all I saw was an ad server.

Interesting details would be soundcard model, sampling rate, operating system and PC processor speed. 

I think the process could be simulated with a delay driving an LED locally to see if the concept performs to your expectations. Possibly, this has already been explored.

Ernie (W7LHL) and I experimented with bistatic radar on 24 GHz to measure reflections and quickly found the software timing problem to be insurmountable using available hardware and software.

At any rate, this sounds like a very interesting experiment. Thanks for sharing your experiences.
