SHIP COMPLEX OF RADIOELECTRONIC COUNTERACTION Russian patent published in 2004 - IPC

FIELD: radio engineering, provides radioelectronic protection of ships due to creation of impulse and masking interference to electronic aids of the enemy aimed in frequency and direction.

SUBSTANCE: the ship complex of radioelectronic counteraction has a device for measurement of the direction to the source of radiation, control device and a counteraction aid including a storage and frequency reproduction aid and an interference transmitter, the device for measurement of the direction to the source of radiation has portside and starboard amplitude direction finders, each including N identical receiving channels of series-connected receiving antenna, high-frequency amplifier, power divider and a receiver with a wide dynamic range, the directivity patterns of the receiving antennas of the receiving channels intersect in a level of 0.5 and in the sum overlap a sector of 180 deg., device of separate summation of signals of the even and odd receiving channels of the portside and starboard amplitude direction finders, whose inputs are connected to the second outputs of the power dividers of the receiving channels, and the outputs - to the frequency measuring devices of the even and odd receiving channels, device of analog-to-digital conversion and preliminary processing, whose inputs connected to the outputs of the amplitude direction finders, frequency-measuring devices and the first outputs of the starboard and portside bearing specifiers, and the input-output-to the automatic control system, the second outputs of the portside and starboard bearing specifiers of the frequency storage and reproduction device, whose third input is connected to the first output of the automatic control system, and the outputs - to the portside and starboard interference transmitters, the second and third outputs of the automatic control system are connected to the inputs of the portside and starboard bearing specifiers, the automatic control system of the two-sided communication channel is connected to the ship systems providing electromagnetic compatibility, radar situation and control aids of passive jamming.

EFFECT: provided analysis of radio engineering situation, classification of the carriers of electronic aids of the enemy, enhanced efficiency at a saturated radar situation.
