| 摘 要： | 主动声呐系统中,平台运动会导致目标回波信号存在多普勒频偏,目标的径向速度会估计错误.文中推导了本舰运动产生多普勒频偏的原因和两者之间的关系,并结合主动声呐的工作特点,提出在接收机和发射机同时进行舰速补偿的方案,可以实时响应舰船运动状态变化,准确补偿本舰运动引起的多普勒频偏.提出在发射机信号源中采用插值法,通过改变发射信...

| Abstract: | In active sonar system,the velocity of target will be estimated incorrectly because of Doppler frequency shift in the echo signal,which is caused by platform moving.The reason how the Doppler frequency shift is caused is given.A method that ship speed compensation should be executed both in transmitter and receiver is presented given the characteristic of active sonar.The method can responds rapidly to the change of moving status of the ship and can compensate the Doppler frequency shift caused by ship movi... |
