应用于旋转导弹制导系统的宽带干涉仪,在两个信号相乘以前,以一个固定量延迟一个天线探测到的雷达信号,以一个变化量延迟另一个天线探测到的信号。在乘法装置里被固定量延迟的信号首先在相位上要导前90~0。乘积信号同旋转轴轴和目标视线之间夹角的正弦成正比,它输到限幅积分器里被积分,其输出与弹上陀螺仪传感信号相加,得出的和信号决定了可变延迟量,而积分器输出控制陀螺仪从而对准雷达信号方向,并控制导弹驾驶仪将导弹自动导向目标。
A wideband interferometer for a rotating missile guidance system delays the radar signal detected by one antenna by a fixed amount and delays the signal detected by the other antenna by a variable amount, before multiplying the two signals. The signal delayed by a fixed amount in the multiplying means is first guided 90 to 0 in phase. The product signal is proportional to the sine of the included angle between the axis of rotation and the target line of sight, which is integrated into the limiting integrator and added to the sensed gyro sensor signal. The resulting sum signal determines Delay the delay, and the integrator output controls the gyroscope to align the radar signal direction and control the missile pilot to direct the missile to the target.
