METHOD AND PROTECTION DEVICE AGAINST ANTI-RADIATION MISSILES (ARM) FOR TARGET PRECISION TRACKING RADAR

摘要

A method is proposed for protection against anti-radiation missiles (ARM) of a radar station (RS) for target precision tracking radar. The method consists in using of distracting emitters (DE) with frequency and temporal parameters of radiation equal to the similar radar radiation parameters and characterized by interruption mode of radar emission and emission of DE is realized during the pauses of radar emission and in time of each pause at least consecutive DE emissions are realized and the total time of DE emission in each cycle should exceed the radar emission time. And also the DE are located in the vertexes of convex polygon, one of them is a radar site, and within the area of ARM homing heat spatial selection, and period of radar emission is specified less than the time constant of ARM homing loop. The device realizing said method consists of N DE with agents connected by N communication channels to the agent of DE control unit connected to radar control unit by data exchange wires. Each DE consists of tandem connected agent, transmitter control block, DE transmitter connected to DE aerial by directional coupler. Control block is connected to the second output of directional coupler is accessed to the port of DE control unit. DE autonomous operation is provided by feed element, connected to power inputs of appropriate units and power converter of DE transmitter.
