    • The invention relates to monopulse radar for automatic angle tracking of a moving target, which prevents angle tracking errors from occurring when the polarization of the received signals is orthogonal to the polarization of the radar receiver. The monopulse radar comprises two monopulse clusters (4, 5) tuned to the same frequency band and arranged to receive mutually orthogonal polarizations; only one of these clusters lends itself for the transmission of r.f. signals. When supplied sum and difference signals by the two clusters (4, 5), the receiver (8) produces the angular error signals required to keep the radar directed at the target. The error signals are determined by the amplitude ratio between the difference signals and the sum signal from the first cluster or by the amplitude ratio between the difference signals and the sum signal from the second cluster, depending on the ratio between the sum signals from the two clusters.
    • 本发明涉及用于移动目标的自动角度跟踪的单脉冲雷达,其用于当接收信号的极化与雷达接收机的极化正交时发生角度跟踪误差。 单脉冲雷达包括调谐到相同频带并被布置为接收相互正交的偏振的两个单脉冲簇(4,5) 这些集群中只有一个集合适用于r.f的传输。 信号。 当通过两个集群(4,5)提供的和差信号时,接收机(8)产生将雷达指向目标所需的角度误差信号。 误差信号由差信号和来自第一簇的和信号之间的振幅比或由差信号与来自第二簇的和信号之间的振幅比决定,这取决于来自两个信号的和信号之间的比率 集群。
