Annotations languages:

Appearance of false targets on the display screen radar may be by accompanied of air objects with the large effective surface scattering; it is cause by the detection threshold exceeding of echosignals that are receive by the side lobes of the antenna pattern. The dependence of the detection range by the surveillance radars of "old" park from the effective surface scattering value of air objects is analysed. A variant of implementation the device of suppression the side responses in the surveillance radar of "old" park by meter range without their substantial upgrading is offered.
Keywords: radar, the effective surface scattering, the side lobes of the antenna pattern, suppression device of side responses
