The main difference between SH-60B and F is the way they fight against submarines. The B version mainly depends on the sonars on the CG and DDGs to find the targets, then it flies to the suspect area, using 25 tubes sonar buoyages and magnetism detector to make sure the target position for following combat using torpedo. The F is used for short range anti-submarine purpose around the carrier and depends on its own AQS-13F suspensory sonar to detect the submarine.

SH-60B和F型之间的主要区别为他们反潜的方法不同。B型主要依赖巡洋舰和驱逐舰上的声纳发现敌潜艇，然后飞近可疑区域，使用其25管的声纳浮标和磁异常探测器对目标精确定位，随后发起鱼雷攻击。F型则用于航母周围的短距反潜，主要依赖其AQS-13F悬吊声纳探测雷达。

The new suspensory sonar would be AN/ASQ-22 by Ratheyon, with a 2,550 feet rope. The 25 tubes sonar buoyages of B version is kept onboard. For hunting enemy ships, SH-60R gets a AN/APS-147 ISAR radar.

新的机上吊放声纳为雷声公司的AN/ASQ-22雷达，吊放距离765米。B型的25管声纳浮标被保留。

The purpose of this thesis is to reserch and design a digital fish torpedo SONAR pulse detect system, to solve some defect which exist in traditional SONAR, to accomplish real-time detect the aim and judge the aim's type and estimate the center frequency, angle, dsintance, repeat period of target, to follow the fast moving target, as well as to adapt the system to different flank three sub-array types without the limitation of installation place.

本文的目的在于研究并设计数字式鱼雷声纳脉冲侦察系统，解决传统声纳中存在的一些弊端，实现对鱼雷脉冲信号的实时检测，以及对信号的种类，中心频率，目标的方位，距离信息，重复周期的估计，对快速运动目标的跟踪测距，使系统不受安装场合的限制，适用于不同的舷侧三元子阵。

No doubt, the more the information, the better the processing effect will be.
