CORRELATION SIGNAL DETECTOR Russian patent published in 2013 - IPC G01S3/802 

FIELD: radio engineering, communication.

SUBSTANCE: correlation signal detector has a discrete antenna array (DAA) made in a certain manner, having N non-directional passive and M active-passive electroacoustic transducers, corresponding I information transmission channels, a beam pattern control unit, a unit for calculating relative coordinates of DAA elements, a threshold device, a decision threshold computer, an indicator, a unit for controlling active-passive DAA elements, as well as correlation beam pattern former with signal time delay. The correlation beam pattern former with signal time delay employs I/k squaring devices, outputs of which are connected to corresponding I/k inputs of a squared process adder, where 1≥k>1, and between the I/k squared process adder and a correlation computer, there is an additional multiplier, the input of which is connected to the output of the I/k squared processor adder, and the output of the multiplier is connected to the second input of the correlation computer.

EFFECT: simple design of the detector, faster operation of the object detection and direction-finding channel.
