TECHNIQUE OF SIGNAL PROCESSING DURING AMPLITUDE PSEUDOMONOPULSE DIRECTION FINDING Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: proposed technique includes following operations: reception of signal by four-element monopulse antenna system with elements 1, 2, 3, 4, formation of two sequences of signals 1+2, 1+3, 3+4, 2+4,...3+4, 2+4, 1+2, 1+3 by cross switching and summing of signals, amplification of received signals, their standardization and detection by amplitude, subtraction of signals detected by amplitude, formation of normalization signal from amplified signals by method of correlation reception, demodulation of subtraction results by manipulation frequency with phase shifts 0 and 90 degrees. Error signals in direction finding planes are isolated in this case. EFFECT: widened transmission band, increased range of action of direction finder, reduced dissipation losses during processing. 2 dwg
