Problem statement. The method of setting coherent interference is known as an effective means of electronic warfare (EW) with anti-aircraft guided missiles (SAM) with active and semi-active homing heads (GOS). This method also works well against ground-based tracking radars (radars). Its application introduces unremovable errors in determining the angular coordinates of the target in direction finding devices. It is possible to increase the efficiency of the active interference station (SAP) by using promising methods of processing the probing signal, in particular, using the phase separation algorithm, which is investigated in the presented article.

Goal. The purpose of the article is to determine which characteristics are decisive in the algorithm of coherent interference, based on the method of processing the probing signal with phase separation.

Results. The article models and analyzes a coherent interference setter using a probing signal processing algorithm to create a set of false targets at different time intervals. The dimensionality of the signal sequence with phase separation and its effect on the effectiveness of aircraft protection are considered separately.

Practical significance. The article shows the possibility to increase the efficiency of coherent interference systems when using relay signals with varying phase characteristics.
