APPARATUS FOR DETECTING SIGNALS AND DETERMINING DIRECTION OF SOURCE THEREOF Russian patent published in 2013 - IPC G01S3/00 

FIELD: radio engineering, communication.

SUBSTANCE: apparatus for detecting signals and determining the direction of their source 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 beam pattern former with signal time delay. The beam pattern former further includes memory and a unit for determining the detector average response value, with a subtractor being able subtract the detector average response value from the memory output signal.

EFFECT: reducing the number of operations when generating detector response by half, simple design of the detector, fewer requirements for processing means while maintaining efficiency of the detector to solve tasks, high speed of the detection channel and accuracy of finding the direction of objects.
