METHOD FOR CONCEALMENT OF MOBILE OBJECTIVE FROM RADAR SURVEILLANCE FROM SPACE Russian patent published in 2007 - IPC F41H3/00 

FIELD: deception of ground mobile objectives from space radar systems.

SUBSTANCE: according to priory known geographic disposition of the route of the objective motion and the parameters of the orbit of the space radar, the time moment of fly-by of the space radar of the points of the minimum range to it and the respective angular altitudes and the azimuth corresponding to them are computed. For final specification of the time schedule and the directions of radar surveillances on the basis of the priory known parameters of orientation of the aerial directional pattern of the space radar the angular altitudes and the azimuth of the direction of the radar surveillance are determined from a great number of the angular altitudes and azimuth of directions to the points of the minimum range to the radar. For preliminarily analysis of the terrain deception properties along the route of motion appearing at a various orientation of the direction of radar surveillance on the basis of the priory known location and altitude of the natural and artificial objectives of the terrain sections located on the route of motion, and the altitude angles and the azimuth of direction of the radar surveillance for each selected moment of fly-by the orientation and the dimensions of the areas of concealment - areas of radar superpositions and radar shadows are computed. To simultaneously reduce the efficiency of radar surveillance and minimize the service life of the mobile objective on the basis of the priory known overall dimensions of the mobile objective the zones of concealment providing the reduction of the level of detection and identification are selected. The mobile objective is moved on the route of motion with due account for its speed and the distance between the zones of concealment in the internals between the moments of fly-by of the space radar, and the mobile objective is stopped at the moment of fly-by in the zones of concealment providing for the preset level of reduction of detection and identification in the zones of radar shadows at low angular altitudes of the direction of radar surveillance and in the zones of radar superposition-at high angular altitudes.

EFFECT: reduced level of detection and identification of a ground mobile objective at a radar surveillance by space radar.
