METHOD OF CALIBRATION OF RELATIVE POSITION OF DATA UNITS IN SYSTEM OF SHOT DETECTION Russian patent published in 2009 - IPC G01S5/22 

FIELD: physics; measuring.

SUBSTANCE: used for calibration of the relative standing of data units in system of detection of a shot. Approximately determine the relative standing of data units; carry out at least two shots in known directions from the different points which co-ordinates are known; determine differences of times of arrival of barrel and shock waves for each of data units and for each shot; determine the relative standings of data units which have underload discrepancy of time differencies at least for two shots. Also for neutralisation of deterioration of performances of data units in system of definition of co-ordinates of a point of a shot by means of several data units spot arrival times to data units of shock waves from the executed shots then carry out performance of a regression by a method of the least quadrates for arrival times to data units of a shock wave for definition time measuring are non-viscous, then yield the control of the contribution of each data unit in quantity measuring of time for several shots are non-viscous and carry out appointment to each data unit of the weight coefficient, which inversely proportional contribution of the data unit in non-viscous time measuring.

EFFECT: increase of performances of data units in system of definition of co-ordinates of a point of a shot.
