AND You can null electronically using a "servo" type software routine, then the phase shift from that will indicate your target. Best done using DSP though.
Look at any Tesoro detector, VERY simply to understand. Simply replicate the action of this in VHDL or DSP code. If you implement an IFT you will produce peaks like a comb filter, where each will spit out a harmonic, if you treat the output of each of these "channels" like an array, you can derive and algorithm to combine the processed data to "fingerprint" targets.
I have this idea and drew this up over 20 years ago. i even put the document on here that I sent to Garret and Whites (Garrett stole the idea IMHO and released the GTi series...Yup even the NAME was the same as my idea - The Garret DigiDec GTi).
I don't care about the "still light years ahead" detector designs I drew up anymore, you're ALL welcome to them, as I'm not longer interested in detectors. I have a project with Dave Emery which will now probably NEVER be used commercially but which is an INCREDIBLE machine based on entirely new working methods NEVER before used.
I intend to use it to spend the next few years working in Alaska and Australia in the gold fields making more gold that I ever could selling detectors.
