ARRANGEMENT FOR SUPPRESSION OF ECHO-SIGNALS, RECEIVED BY A LATERAL DIRECTIONAL LOBE OF AN ANTENNA Russian patent published in 2007 - IPC G01S7/36 

FIELD: the invention refers to the field of radiolocation and may be used in impulse radars for suppression echo-signals, received by a lateral directional lobe.

SUBSTANCE: These results are achieved at the expense of that the known arrangement for suppression of echo-signals, receiving by a lateral directional lobe having an antenna, a receiver, a detector-integrator, a memory unit, a comparison arrangement connected in series, and also "n" channels of forming threshold level each of which has the first and the second valves, whose outputs are connected with "n" inputs of an adder connected with its output to the second input of the comparison arrangement whose output is the output of the whole arrangement. At that the first inputs of the first valves in each channels are connected to the output of a detector-integrator and the second, also as the second inputs of the second valves - with "n" outputs of a control unit, whose "n+1" output is connected with the second memory unit and the input - with the output of a driving oscillator, in each "n" channels of forming threshold level are introduced in series connected with the output of the first valve of the channel memory unit, a rating arrangement and a calculator of the threshold level, whose output is connected with the first input of the second valve.

EFFECT: increases resolution according to an angular coordinate.
