FIELD: radar engineering; systems for searching and tracking airborne targets. ^ SUBSTANCE: proposed device has rotary directivity pattern receiver, azimuth sensor, amplitude-to-code converter unit, and secondary processing unit; output of rotary directivity pattern receiver is connected to input of amplitude-to-code converter unit and group of azimuth sensor outputs is connected to group of secondary processing unit inputs. Newly introduced in device are parallel delay line unit, subtracter, coder, and adder; group of amplitude-to-code converter unit outputs is connected to second group of subtracter inputs and through parallel delay line unit, to first group of subtracter inputs; subtracter also has group of outputs connected through coder to first group of adder inputs; second group of adder inputs and group of outputs are respectively connected to group of azimuth sensor outputs and to second group of secondary processing unit inputs. ^ EFFECT: enhanced precision of finding target direction. ^ 1 cl, 2 dwg |
