Until the arrival of Precision Impulse, the only detonation phenomenon known to exist was that described as “deflagration to detonation transition” or DDT, whereby the air-fuel mixture in a contained space begins burning at the point of ignition and conflagrates or spreads throughout the rest of the space until all fuel is burned. This type of detonation does produce power, but that power is limited by the “incoherent” timing of the long fuel burn. It was this limitation that led the Precision Impulse team to ask a critical question: What would happen if one could get all the air-fuel mixture to burn at exactly the same instant?
The question of timing had never been asked until then. But timing is everything if you hope to create a device capable of producing the combined effect of firing simultaneously.
Precision Impulse’s remarkable discovery enables squared power: When stacking two or more incoherent seismic sources, the amplitude as seen by the geophone array is found to be the square root of the number of combined sources. However, using the same amount of fuel, fully coherent operation, as delivered by Precision Impulse’s sources, allows for a linear increase in amplitude when two sources are fired simultaneously. In other words, the geophone response will be increased by N times the response due to a single source as opposed to the square root of N that is expected for conventional, non-coherent sources. The SNR therefore improves at 6 dB per doubling of the number of simultaneous sources as opposed to 3 dB for incoherent sources.
