METHOD AND SYSTEM OF DETERMINING TRAJECTORY OF SUPERSONIC PROJECTILE Russian patent published in 2009 - IPC G01S3/808 

FIELD: physics; measurement.

SUBSTANCE: present invention can be used for determining the trajectory of a supersonic projectile. At least the initial part of signals is measured, containing information only on impact wave, using five or more acoustic sensors, spread out in space such that they form an antenna. From this measured initial part of signals, the difference in arrival time for a pair of sensors is determined. A genetic algorithm is applied to the initial chromosome, which contains initial estimated parameters of the projectile trajectory. For a given number of generations, projection errors are calculated for solutions, obtained from chromosomes from the genetic algorithm. The ratio of solution with the least values of projection errors to the ambiguous solution is calculated, and if this ratio is greater than a given value, the solution with the least value of calculated projection error is chosen as the correct trajectory of the projectile.

EFFECT: more accurate location of the firing point of a supersonic projectile, at a considerably long distance.
