METHOD OF SELECTION OF INFORMATION ON MOVING AIR OBJECTS WITH PROVISION FOR SCREENING OF FALSE ROUTE RADAR INFORMATION AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 1997 - IPC

FIELD: radiolocation, additional screening of false route information under conditions of active reflections from underlying surface. SUBSTANCE: system for automatic lock-on and tracking of moving air objects includes airborne radar 1, system 2 for primary processing of radar information, system 3 for secondary processing of radar information, unit 5 generating route information to user, gear 4 selecting information on moving air objects with provision for screening of false route information. This gear includes storage 4.1 of list of radial velocities for each detected route of air object, device 4.2 computing sum of absolute values of radial velocities, threshold device 4.3, unit 4.4. generating route number, former 4.5 generating information on list of correspondence to storage, storage 4.6 of list of correspondence, comparator 4.7 of numbers of airborne radars and unit 4.8 canceling commands Given gear makes it possible to make decision automatically to what a priori known distribution of independent values of radial velocities values of radial velocities for each route of air objects relate - to distribution of values of radial velocities for air objects or to distribution of radial velocities for reflections from underlying surface. As result false information is screened. EFFECT: increased efficiency of screening of false route information with due account of differences of a priori distributions of values of radial velocities measured independently by echoes and reflections from underlying surfaces, with due account of storage and usage of information on value of radial velocities obtained in several measurements by which route of air object is formed. 2 cl, 1 dwg
