    • A pulse radar apparatus (2) for target (14) tracking is designed to provide angular error data representing the deviations of projectiles, fired from a gun (3) at the target with respect to the target position line. The l.f.-signal processor of said radar apparatus comprises:a. a signal analyzer (17) having a filter bank for determining Doppler spectral components of echo signals received from the fired projectiles within the target range gate (23) and l.f. detected;b. selection means (18) for selecting the projectile Doppler spectral components from the signal analyzer (17) and filter bank; andc. an angular error generator (24) for generating angular error data from the Doppler spectral components selected by the selection means (18) to correct gun aiming values calculated by a fire control computer (9).
    • 用于目标(14)跟踪的脉冲雷达装置(2)被设计成提供角度误差数据,其表示相对于目标位置线从靶(3)射出的射弹的偏差。 所述雷达装置的信号处理器包括:a。 信号分析器(17),具有滤波器组,用于确定从目标范围门(23)和l.f内的被发射射弹接收的回波信号的多普勒频谱分量。 检测到 b。 选择装置(18),用于从信号分析器(17)和滤波器组中选择射弹多普勒频谱分量; 和c。 角度误差发生器(24),用于从由选择装置(18)选择的多普勒频谱分量产生角度误差数据,以校正由消防控制计算机(9)计算的枪瞄准值。
