Прямолинейные траектории скрытного движения воздушного объекта в зоне обнаружения бортовой доплеровской радиолокационной станции

Труды МАИ. 2015. № 84.

An onboard radar operating in the impulse–Doppler mode has the characteristic features of the detection zone. The feature lies in the fact that at every point of the detection zone an airborne object has a sector of directions such as the onboard Doppler radar will not detect it as long as it moves in these directions. This sector is called the sector of invisible motion directions of the flying object. Due to these features, there exist hidden trajectories such as objects which are flying along such trajectories are not detected by an onboard Doppler radar such as AWACS radar. The most hidden trajectories are non-linear path with a variable curvature. However, under certain conditions, rectilinear secretive trajectories also exist. They are easier then nonlinear hidden trajectories, and therefore, are of a particular interest.
