Visualization and localization of the radio spectrum to one gigaHertz.

Project goals:

to acquire wide chunks of spectrum from 0.1 to 1000 MHz

to identify the location, nature and origin of each signal.

to synchronize the clocks of wideband receivers to within 50 nanoseconds

Project priorities:

1) partition celestial signals from terrestrial signals.

2) determine the heading and variation of celestial signals.

3) determine the location and modulation of terrestrial signals.

Questions that Must Be Answered

How many clocks are necessary to uniquely locate a signal?

one source and one receiver (sink) limits the location of the source to a the surface of a fuzzy sphere surrounding the sink
	if:
		a) the source is modulated
		b) the propagation path and delays are known

What are the options for keeping the clocks in sync?

options for time coded signal

digitize both signals

sync both times, accept whatever slewing is occurring as long as sync is good enough

sync n times

Solutions

The most important part of this work is creating an effective method for determining the time of arrival of signals emmanting from an unknown origin.
