Method for detecting trajectory of rifle projectiles, involves determining azimuth direction of point with minimum distance of projectile trajectory from radar by interpolation of measurement value consequence to time point

摘要

The method involves estimating a parameter such as absolute projectile speed and minimum distance of projectile trajectory from radar and a time point at which the projectile is passed with minimum distance. Measurements in non-linear parameter fit are adapted to analytic context of time characteristics of angular direction in azimuth such that trajectory direction in azimuth is estimated. Azimuth direction of a point with the minimum distance of the projectile trajectory from the radar is determined by interpolation of a measurement value consequence to the time point.
