METHOD FOR GENERATION OF RADAR JAMMING Russian patent published in 1997 - IPC

FIELD: radars. SUBSTANCE: method involves receiving pulses of radar to be suppressed by means of searching unit of jamming station, measuring azimuth and heading angular coordinates of radar with respect to jamming station, measuring radar pulse rate period or duration of pulse bursts (when Doppler-effect radars are suppressed), measuring traveling time for passing electromagnetic waves from radar to jamming station and back to radar (2t_p), emitting jamming pulses in response to each radar pulse or in response to first pulse of each pulse burst using delay time τ_d, emitting jamming signal of maximal power (P_max) for τ_m, dropping jamming power down to level of P_min and keeping this level for time which is equal to difference between radar pulse rate period (or burst duration) T_e and τ_m. Value of P_min for each radar to be suppressed conforms to condition: . Values τ_d and τ_m are calculated using equations: τ_d = τ_e - 2t_p, or equations: , where c is electromagnetic energy spreading speed, ^Rmin is minimal effective distance between radar and object to be concealed. Value of 2t_p is determined by ranging radar or object radar is located in using jamming station. EFFECT: decreased mean power of jamming, decreased power consumption by emitter. 5 cl, 9 dwg
