Abstract

 One of the main methods widely used in active noise jammer cancellation is to form concave (zero) zones in the antenna pattern of radar towards the jamming source by using adaptive phased array antennas or auto compensate sidelobes. The effective protection of radar from active noise jammer is primarily determined by the level of the buds on the antenna pattern side, where active noise is most likely to be affected. In fact, due to the motion of the radar antenna or interfering source, the active noise becomes non-stationary when the radar system has "service" intervals. Automated active noise compensation systems are built base on forming weight vectơs by reversing the obtained matrix (called direct inverse correlation matrix (NOM) combined with the algorithm Linear weight vectơ interpolation allows the maintenance of non-stationary active noise compensatory quality.
