FIELD: radiolocation, increased resistance of radars to reconnaissance. SUBSTANCE: method increasing secretiveness of parameters of radar is based on modulation of signal parameters. In accordance with invention form of radiation pattern of radar is changed in process of signal transmission and for this amplitude or phase distribution of field of radar antenna or parameters n≥1 of additional radiators are changed . Form of radiation pattern is changed with period less than duration of emitted signal. EFFECT: raised secretiveness of parameters of radar. 4 cl
