FIELD: radar systems; additional selection of false route information at intensive reflection of underlying surface. SUBSTANCE: device for automatic lock-on and automatic tracking of moving air objects has radar 1, primary radar information processing system 2, secondary radar information processing system 3 and route information output unit 5; besides that, device is provided with false route information and moving air object selection unit 4 which consists of radial velocity list storage for detected routes of air objects 4.1, device for calculation of sums of absolute magnitudes of radial velocities 4.2, threshold device 4.3, unit 4.4 for forming commands for output of information to correspondence list storage, correspondence list storage 4.5, radar number comparison unit 4.6 and command cancellation unit 4.7. Device 4 makes it possible to automatically determine a priori known distribution of independent magnitudes of radial velocities for each route of air objects: distribution of magnitudes of radial velocities for air object or distribution of radial velocities for reflection from underlying surface. EFFECT: enhanced efficiency of selection of false route information due to taking into account differences in a priori distributions measured independently by echosignals of magnitudes of radial velocities for air objects and for reflection from underlying surface, as well as due to accumulation and record of information on magnitude of radial velocities obtained from several independent measurements according to which air object route is formed. 1 dwg |
