利用舰船水压场的作用而动作的水雷水压引信,在布放后会受到水中各种水压场的自然干扰及人工干扰。对这些干扰,国外的资料曾有过如下的分类及论述。 1.长周期干扰:主要是潮汐干扰,资料认为潮汐水位随时间的变化接近于正弦波,因此,可当作正弦波进行工程计算,以选择接收器参数。另外,不同密度层的内浪及在近岸地区由大风所引起的增水和减水,也是一种长周期干扰。 2.短周期干扰:指海浪干扰。某些引信设计资料指出,只要将引信的延时时间设
The use of naval water pressure field of the action of the mines and water pressure fuze, will be placed in a variety of water pressure field of natural and artificial interference. For these disturbances, foreign information has been classified and discussed as follows. 1. Long-period interference: Mainly tidal interference, the data suggest that the tidal level changes with time close to the sine wave, therefore, it can be used as a sine wave for engineering calculations to select the receiver parameters. In addition, the internal waves of different densities and the water and water losses caused by strong winds in the nearshore are also long-term disturbances. 2. Short-cycle interference: refers to the wave interference. Some fuze design information pointed out that as long as the fuze delay time set
