本发明论述供脉冲转发式干扰机使用的可变延时装置。雷达距离跟踪系统可用这样的方法来干扰,即对于所接收的雷达系统的每一个脉冲,干扰机发射一相似的干扰脉冲,只要干扰脉冲比目标回波脉冲强得多,并且相对于目标回波脉冲稍有延迟。而且,通过增加干扰脉冲(它构成假目标)的时延可以使距离跟踪系统跟随此假目标直到丢失真目标。如果距离跟踪系统是火控系统的一部分,则被控武器要么不开火,要么就向假目标开火。在目前完成这种干扰的设备中,给一固定周期设置了一个起始延迟,在起始延迟之后, The present invention discusses a variable delay device for use with a pulse repeater jammer. The radar range tracking system can be interfered in such a way that for each pulse of the received radar system the jammer transmits a similar jamming pulse as long as the jamming pulse is much stronger than the target echo pulse, Pulse slightly delayed. Moreover, by increasing the delay of the disturbance pulse (which constitutes a false target), the distance tracking system can follow this false target until the true target is lost. If the distance tracking system is part of a fire control system, the controlled weapon either does not fire or fires on the false target. In a device currently performing such interference, a start-up delay is set for a fixed period, and after a start-up delay,
