  • anomalous explosives long range locator/detector spectrum electric signal analysis me

    Anomalous explosives long range locator/detector spectrum electric signal analysis measured on the tip of whip antenna via x10 probe connected directly to the spectrum analyzer input





    fig.1 fundamental (1st harmonic) @7.5 KHz and 3rd @15 KHz and 5th @37.5 KHz all of the same amplitude!!



    fig.2 odd harmonics from 1st to 11th shown with a 6 - 100 KHz span without any diminishing amplitude effect!




    fig.3 6 to 300 KHz span, spectrum analysis of locator odd harmonics 1st to 39th shown without any observable reduction in amplitude!!

    ------------------------------------------------------------
    NOTE: 1ST HARMONIC SHOWN WITH DISTORTION/NOISE BECAUSE OF RANGE LIMITATION 9kHZ OF ANALYZER USED. LOCATOR'S SQUARE WAVE SIGNAL OUTPUT WAS SET AT 7.5 KHz (1ST HARMONIC FUNDAMENTAL)


    how is that possible? WTF!!

    The explosives lrl's whip antenna is feed with a square wave signal, so it is expected as shown that there will be only odd harmonics existing but their amplitude is not diminishing?!!....

    CAN THIS BE PROOF OF LONGITUDINAL WAVES??

    ANY IDEAS ARE WELCOME...
