A method for protection of coherent-pulse radar stations (RS) against combined jamming wherein useful signals and noise are received by the main and compensation channels of RS, with compensation of active noise interference through control of weight coefficient of polarization (or spatial) filter, with carrying out selection of useful signals, for instance with application of discrete Fourier transformation, with reveal of useful signals on background of passive noise and with representation of radar targets detected on monitor of the RS. Time intervals for adjustment of weight coefficients are determined through evaluation of distribution of coefficient of inter-channel correlation (CIC) by development of range, in particular the CIC values during development of range are calculated in sequence at intervals lengths of which correspond to time of adjustment of weight coefficient of auto-compensator, with storing. Then among those values the maximum one is found with storing at which interval of time (range) it is observed. In the next development of range adjustment of weight coefficient of auto-compensator is performed at that time interval (range) only. |
