MODE OF DETECTION OF AN OBJECT'S TRAJECTORY Russian patent published in 2007 - IPC G01S13/58 G01S13/72 

FIELD: the invention refers to radiolocation and may be used for detecting of objects' trajectories in surveillance radar stations with phased array.

SUBSTANCE: the mode of detection of an object's trajectory is based upon an additional address to the object in the strobe of confirmation about detection of the object, the strobe is initiated through a small interval of time after detection of a reflected signal during regular surveillance. At that the value of the interval is chosen far less than the interval of time of addressing to the object in the strobe of capturing the trajectory. At that an additional "quick" addressing to the object in the strobe of confirmation of detection of the object allows: firstly, significantly accelerate measuring of the speed of high-speed objects and for certain execute extrapolation of coordinates and that is extremely important for securing effective destruction of such objects at sufficiently large distance; secondly, significantly decrease the number of reflections from passive interferences and reduce by this the number of trajectories formed according to them.

EFFECT: reduces number of false trajectories formed according to the reflections of passive interferences.
