SINGLE-CHANNEL MONOPULSE RADAR SYSTEM DETERMINING BEARING TO TARGET Russian patent published in 1998 - IPC

FIELD: radiolocation. SUBSTANCE: invention may be used for single-channel reception of signals and for extraction of angular information in amplitude sum-and-difference monopulse target tracking with intrapulse phase manipulation of probing signals with M sequence. In compliance with invention integration of sum signal with difference signals of azimuth and elevation is carried out on high frequency in turn with repetition period of probing signals by change of phase of difference signal and its later summing with sum signal. Division of signals converted by frequency and amplified is performed by means of their correlation processing in two stages. At first stage additive mixtures from quadrature components of sum (difference) with phase manipulation and of demodulated difference (sum) signals are formed in quandrature channels. At second stage quadrature components of demodulated signals are extracted by way of their collection in integrators. Divided quadrature components of signals are converted to digital code and are used for isolation of signals of angular error. EFFECT: improved functional characteristics of radar system. 5 cl, 8 dwg
