The article is devoted to the analysis of results of the visual simulation of working of the impulse interference compensator with the action algorithm based on the Double Discrete Hartley Transformation (DHT) with simultaneous recovery of the affected components of the useful signal in the capstral plane. The block diagram of the recovery (regenerations) algorithm is decribed. It is shown that the essential reduction of the quadrature signal components “blanking” effect is achieved due to recovery of the affected components of the useful signal in the capstral plane and due to reiterated DHT. As a result, the modules of the spectral density of the target echo-signal in the certain phase filters of DHT are not reduced. The efficiency estimation of the compensator working was conducted for the case of operating on coherently-impulse RADAR by asynchronous impulse interferences that strike of one distance discrete of the certain frequency pack.
