手持式潜水员侦察系统
做了进一步改进的手持式潜水员侦察系统采用电池电源（持续工作时间6.5小时），其原型系统是为浅水区反水雷潜水并在对成套设备进行应用研究的基础上制成的。新的潜水员侦察系统还被设计有如下功能，即该系统的高频扫描声呐信号与定位的潜在水雷联系的同时，系统可同时在搜索航线内航行。
该系统主要的搜索传感器是一个前视的、电子扫描（64×1°水平电子束和10°或20°束宽的重直电子束）、高频（500千赫磁）声呐。该声呐能够探测230米内25分贝的目标，并能对须回避的障碍和已布设的水雷目标给出图形。目前，齐耐蒂克公司和英国皇家海军潜水队已成功地对该声呐探测定标球和真实水雷形状的能力进行了试验。
潜水员侦察系统采用长基线主动声学发射装置，该装置要求处于固定在海床已知位置的2台和4台声学脉冲收发两用机（工作在40~80千赫）之间，这样的布设便可对一个独立的固定点进行位置计算。利用上述技术该系统的航行精度可达0.5米，最大航程可达到1 200米。
“如果要在相同时间内探测同一狭长海域，一名装备该侦察系统的潜水员便可完成，但若采用传统的在海床上敷设长反射器的方法则需20名或更多的潜水员。”齐耐蒂克公司介绍说。
这一潜水员侦察系统已经受到10个国家海军的青睐，2个欧州国家海军已报道了正式采购的详细情况。该系统每套售价约10万欧元（12.4万美元）。
The hand-held, battery-powered (endurance 6.5 hours) Diver Reconnaissance System (DRS) is a further development of a prototype system built under an applied research package for shallow-water mine-countermeasures (MCM) diving. It is designed to enable an MCM diver to simultaneously navigate within a search pattern while locating potential mine contacts with a high-frequency scanning sonar.
The primary search sensor is a forward-looking, electronic scanning (64×1°horizontal beams with a vertical beam width of l0°or 20°), high-frequency (500 kHz) sonar. Typically, this sonar can detect a -25dB target at a range of 230m, The sonar can be configured for obstacle avoidance or target location, and has so far been successfully tested by QinetiQ and UK Royal Navy dive teams for its ability to detect calibrated spheres and realistic mine shapes.
The navigation system uses long-baseline active acoustic transmissions．This requires between two and four acoustic transponders (operating between 40-80kHz) to be positioned on the seabed in known positions to calculate an absolute fix. A navigational accuracy of 50 cm is possible with this technique. The maximum range of the navigation system is up to 1,200m.
"If you want to cover the same swath in the same time as can be done by one DRS-equipped diver, but using the traditional method of laying ropes on the seabed for navigation, you would need 20 or more divers."QinetiQ said.
The DRS has already attracted"serious interest"from l0 navies, and detailed discussions about actual procurement were reported with two European navies. The DRS would be available for approximately EUR l00, 000 (USD 124,000) per unit.
