DEVICE FOR DETECTING SIGNALS AND DETERMINING DIRECTION OF SOURCE THEREOF Russian patent published in 2014 - IPC G01S3/802 

FIELD: physics.

SUBSTANCE: in said device, detector response is generated without the effect of the average value of spatial response of the detector on interference and the possibility of receivers of a discrete antenna array to move in space under external forces is taken into account. To this end, the 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, a display, a unit for controlling active-passive DAA elements, as well as a beam pattern former with signal time delay. The fundamental differences between the invention and the prototype lie in that the detector includes an operator panel and the beam pattern former further includes a microprocessor unit capable of subtracting, using a subtractor, the average value of the detector response to interference only from the output signal of a storage device.

EFFECT: novel device for detecting signals and determining the direction of sources thereof with two nonlinear operations in the processing cycle.
