Novel underwater intelligent navigation sound target

Abstract

The invention discloses a novel underwater intelligent navigation sound target. The target comprises a head shell, an electronic cabin section, a sounding section and a propelling section which are connected in sequence. The sounding section comprises a sounding section shell, a sounding control panel and a sounding transducer; the sounding section shell comprises a main cabin body, and a first annular positioning cabin and a second annular positioning cabin which are respectively connected to two sides of the main cabin body; the first annular positioning cabin and the second annular positioning cabin are respectively embedded into the electronic cabin section and the propelling section and then are fixedly connected and linked through a locking assembly; the sounding control panel is fixed in the main cabin body; the sounding transducer is fixed on the lower wall of the main cabin body, and the sounding end of the sounding transducer extends out of the main cabin body. According to the invention, the sounder is carried on the underwater intelligent navigation body; the sounder can make a sound according to a set operation plan, the underwater intelligent navigation body can sailaccording to the set operation plan, so that realistic simulation of sound signals is realized, the underwater intelligent navigation body can perform underwater navigation, water surface navigation and underwater hovering, and dynamic and static simulation of the sound signals can be realized.

Description

technical field [0001] The invention relates to the field of underwater weapons and marine technical equipment, in particular to a novel underwater intelligent navigation sound target. Background technique [0002] Underwater acoustic targets are widely used in the field of sonar and underwater weapons. During the development of sonar equipment or acoustic fuzes for underwater weapons, in order to test their performance, it is often necessary to provide an underwater acoustic target as a target for sonar or acoustic fuze to detect and identify . At present, underwater acoustic targets generally adopt towed, bottomed and suspended types. [0003] The towed sound target is to use a towed platform such as a ship to tow an underwater sounder for operation. The towed acoustic target mainly has the following defects: the system is complex and the cost is high. The towed acoustic target is generally composed of a towed winch, a tow cable, and an underwater sounder, and is towed b...

AI Technical Summary

Problems solved by technology

The towed acoustic target mainly has the following defects: the system is complex and the cost is high. The towed acoustic target is generally composed of a towed winch, a tow cable, and an underwater sounder, and is towed by a ship to work. The system is complex and the results are expensive; The operating water depth is limited, and the underwater towing body in the underwater towing system often has the problem of difficulty in determining the depth, especially when the speed is high, it is even more difficult to achieve a large fixed depth, and the water depth of the towed acoustic target will be strictly limited; The sound field characteristics of the target simulation are not realistic. Since the towed sound target must be towed by a towed platform to operate, and the tonnage of the generally towed platform is relatively large, the noise and wake generated by the towed platform will affect the sound field characteristics of the sound target. Interference, resulting in unrealistic simulation

Both of these two acoustic targets have the disadvantages that they cannot be moved and cannot simulate dynamic targets. At the same time, they also have disadvantages such as difficulty in deployment and recovery, and inconvenient setting of working conditions.
