Description: Discusses possibilities of effective survey radars receivers defence from the hindrances of the combined type. Combination of hindrances implied joint influence of active impulsive and passive hindrances of different origin. The device construction features and efficiency suppression of the combined hindrances are analysed. Proposed device which invariant to a moment influence impulses of chaotic impulsive hindrance.

Keywords: active impulsive and passive hindrances, protecting from the hindrances of survey radar, device of suppression of the combined hindrances
